Welcome to the Samus boards.
For starters, I don't normally critique videos with AIs. You just got here, so here's your freebie.
Watch your d-tilt usage. If you plan on using it as a kill move, you need to learn not to stale it. Remember, z-air does not count towards the stale move count, and it takes 9 moves to completely refresh it. And because z-air doesn't count, nine is actually a substantial number.
With this said, at
0:35 you use grab to pummel, great job. You don't do it
here however, even though you literally landed d-tilt a little bit earlier. I'm also assuming, that immediately after that, you messed up grounded up+b by jumping. Be wary of this.
*In other news,
this is information you should know. As well as the fact that pummeling too fast will mean not all pummels will count towards the stale counter.*
On the concept of pummeling and grabs, I didn't see any pivot grabs. And with the AI being so predictable with landing, I would have thought to see more pivot grabs from you. Work on implementing that in your game and learn all kinds of scenarios where you can do it (reading an air dodge, from jab cancel, after a whiffed aerial, after a projectile, etc..) Pivot grab won't always be there to use alone.
Other things I noticed:
Spiking is great with Samus, but acknowledge that during certain situations,
there can be a better option. For example,
here you could have easily gimped the Wolf, leading to an immediate stock. Learn to tether gimp or at least up+b the ledge for invincibility frames instead of going for the spike.
Also,
here you should have footstooled. What if you had missed that d-air? What if ROB had waited on using fuel to recover (like a human player would?) A commitment like that d-air isn't worth it, especially if you're equal on stocks. Footstool him, then d-air his next recovery attempt after you regain your second jump from touching the ledge.
Your f-air usage is decent. One problem I saw was
this where you f-air canceled into d-tilt, which is great. Learn to space the f-air cancel better though.
Another thing I saw was your d-air spacing. Acknowledge that
it will not work against a competent player on the offensive. If a computer can get through, like
this and
this, what makes you think a human player can't do it. Nearly every character in the roster has a f-air/b-air that can counter your d-air tactic. Use it less, and also learn when you'll need to fast-fall it. Also learn situations where RARing (reverse aerial rush) can be more effective simply because the hitbox comes out sooner.
Also learn that b-air is your spacing punisher and you should be using it if you need to retreat from your opponent (which you will HAVE to do in higher level play.) You did it
here which is nice but was hoping to see it more as well.
Your jab cancel to d-smash roll punisher on Lucario was great. (Not great in a tech sense, but great in a smart sense.) Learn to do this more (punish rolls), as well as more jab cancel options.
And on that note, when you take away someone's second jump (via missile/z-air/etc,), it opens a multitude of options for you. Learn to capitalize on this. From far away, you can time fully charged shot to ALWAYS hit even if they air dodge. From close up, if they return with air dodge, learn to charge d-smash to punish. (Recognize that this will not work on all characters. DK/Lucario with momentum canceling moves (side+b and d-air respectively) are examples of characters that can avoid this. Samus has a move like that as well: bombs.) If you learn to punish these three defensive options: spot dodge/roll/air dodge, and furthermore, learn to apply this knowledge by forcing these situations, you as a player will grow exponentially.
Your bomb usage is rather extraneous. If it works, it works, but otherwise lessen up on that. U+smash as well, although in general your u+smash usage was greatly timed/performed. Also
don't roll towards your opponent with Samus, ever. Away, fine, towards no. I saw it once, don't let me see it again. Only certain characters can get away with forward rolling. If you're interested, look
here for more details.
I believe that's all for now. I'd like to see you against a human eventually, in a high-level match would be even better. You'd be able to get better criticism from me with the latter.
Good luck, and again, welcome to the Samus boards.
EDIT: Where are my manners... your Samus is pretty good for just picking her up! lol It flows nicely and shows you have control over your character.
I would highly suggest you fix your internet connection and play with the Samus players here. You can pick up tips and different playstyles from the following people:
IsmaR and her n-air usage,
Cherry and his u-tilt,
Raigoth with bombs. Also watch videos of
Rhyme and how he spaces f-air,
Carter for his b-air usage,
Jasona with his jab canceling,
n00b and his pivot grabbing, and
Xyro for how he plays in general (I sum up his playstyle with this quote:"good and gay keep the pro players away.") Look out for Xyro's OoS up+b, FF u-air, charge shot and z-air usage especially. If you're looking for creativity and inspiration, the European players are the best at that. Look for
L!te, and more recently,
quiksilver and their respective combo videos. If you need a good wi-fi training partner, I'm sure
KillerJawz would be more than welcome to comply.
Stray away from watching the trick videos you see for Samus. It's good to know and learn them, but otherwise they're not too useful.
Don't play with me online, I'm absolutely horrible on wi-fi and cannot do ****.
Good luck.
