Bowser's the character that impressed me the most; you're good with him at the ground, but you need to auto-cancel his f-airs, like what you do for Ganon's d-air.
Your Kirby's pretty diverse. You seem to use a lot of f-airs, and a few b-airs, because it is his best aerial to FoP. :P I also think that you should ignore his specials, besides his hammer when comboing with it with a grab and Final Cutter against Snake. Oh and you should practice Gonzo Combo. :P Here's the link if you don't know what it looks like:

You're Wario did pretty fine. To be honest d-smash isn't good to use as a punishable move so use f-smash or u-tilt instead; I did use some d-smash too, but that was from auto-canceling d-air afterwards, so lag came and them it made me d-smash. U-air as much as possible when you're opponent's on the air and whatnot, so ya. :P
I dunno about Falco. We played on Halberd and I think you SD'd once or twice. o_o Anyways, try not lasering on the ground, and it's best if you shorthop and then laser, and you were trying. :P Combo more with his throws at a 0 percent or so like jab cancel -> shieldgrab -> d-air -> grab -> d-throw -> n-air/d-air/u-smash/b-air. I also remember you doing f-airs, which isn't good because it doesn't good knockback but decent damage, plus it's laggy. B-airs are your best bet when you're going to rack damage, while n-air should be used sparingly, and d-air for a spike KO.
Maybe you should practice the combos nao or later. ;]
