First, a lot of dashing and when you walk, is not in the best situation so work on finding the best situation for walk instead of dashing, it helps quite a bit.
Also you rush a lot Upsmash and DS, Upsmash is a punisher so use it for well... punish, and DS is used on reaction and OoS. But you might try to wait your Upsmashes for punishing falco's recovery, 'cause you did it quite early and that means you're warning him to don't recover on stage, considering you don't pressure on the ledge.
When you're on air, getting back to the stage, always remember if you have your second jump or not, so you can stall a little with DB1 and get safely to the edge. On your 9th match, you rushed your DS back to the stage and by miracle you didn't die, because a Bair with you DIing out to the edge should have killed you. By the way, on your 9th match you lost beacuse you faired him without enough momentum to get back to the stage, I don't know if you just miscalculated the distance but if you don't that was a terrible mistake, in situations like that (when your opponent doesn't pressure you on the ledge) is better to aim to the edge.
This one is imperative, DON'T DB1 STALL INSIDE THE STAGE IN FRONT OF YOUR OPPONENT. I can't believe how Shugo didn't punished all those jumps>DB1, he could have punished you with every aerial. If that works specially for him, well that's understandable, but is something you must do barely once per match (for baiting mainly) to never, it keeps you on a bad spot, and screaming for a punish.
I noticed you missed a lot of Uairs... but raising, well, that's ok but you have to do it when you're almost 100% sure you're going to score the hit, or you're going to be far up from him if he AD, because if you don't autocancel on the ground, that means a lot of lag (you got killed by this on match 11th).
Try to used more mindgames for your landings and crossovers, because you were getting punished for always going behind Shugo (he could have punished more severely).
Match 11th, 3:23 you used jab when you should have killed him, well that's just an example of a lot of bad punishes, a DB would have been better, but that was a free smash.
At the end of that match, you allowed him to approach and did anything, I guess you just didn't react, but you must not allow that situation, because marth suffers a lot in the edge.
As a minor detail, you failed all your attempts to chaingrab falco, so for instead looking for all the grab, I recomend you to Fthrow twice, then Dthrow once and Fsmash, so you can rack up some damage instead of failing and getting punished.
As an overall, you have problems punishing accordingly the situation, so get familiar with marth for that. Also nicely done gimping falco's UpB, you should pressure him more offstage because he landed safely most the time like you did on the last match.
Hope it helps you
