Sorry that my critique is coming REALLY late...I got tied down with a week-end project.
So...anyways...
I am not going to bother with the second match, since I am commenting on Kirby (chaos_). Quick notes for Marth (yellowroy): Please use u-tilt, f-tilt, and retreating f-air (jump away + C-stick towards direction Marth is facing) more…thanks. Maybe a few grab releases would be nice, too, since Marth has worse throws in this game.
I notice that you fail to look at your opponent. At about 1:14 for the first match, you damaged Meta-Knight and gave him the Shuttle Loop he needed (Meta-Knight was in fallspecial off-stage) to get back on the stage.
Your main flaws seem to be these:
1. (Standing) Inhale on the stage – try a dash to short to Inhale, or a ledge-hopped Inhale. Those are better set-ups for a successful attack.
2. Stop using Stone in range of a Shuttle loop.
3. Your technical skill is inconsistent; it needs more perfecting (especially SHFFing).
4. Know the Marth match-up, since this is one of Kirby’s worse odds…although I will not go into detail here, I say to not use d-throw, let Marth approach (since camping wins), and counter-pick Rainbow Cruise (Final Destination against Marth’s stage-ban).
5. Your aerial spacing is ineffective.
6. Trying to edge-guard Meta-Knight...>_<...is a good way to lose.
Your minor flaws:
1. Drop the d-air spam…
2. Less pummel after grabbing at low percentages…
3. End Mach Tornado closer to the ground.
What can you do to improve?
1. Learn the proper times for your specials:
i. Inhale – perfect the set-ups.
ii. Stone – high, off stage recovery or punishing lag/predictability. Stop using it close to the stage…
2. Less d-air…
3. Get your tech skill more consistent – Short-hopping and fast-falling.
4. If you fight a Meta-Knight Mach Tornado spammer, try f-smash rather than Inhale.
5. Use smash-DI when hit and immediately use b-air. This needs to happen in the first several frames. This helps your recovery and lets you livelonger (sic…spell checker sees this as a compound word).
6. Use C-stick to help with your aerial spacing.
7. Never approach if you can help it.
Epic moment:
4xu-tilt at 49-51 seconds first match.
Practice makes perfect! You are a decent Kirby player and can follow up your attacks well (such as d-air to b-air), so you definitely have potential.
