If I could play friendlies with you, I would because of how nicely you asked. :D
But... My Wii broke down this august, and it had homebrew in it, so I can't send it in for fixing. I still don't have a Wii, and my only means of laying the game is through smashfests and tourneys all over PR (so I'm forced to pay-to-play offline only). Sadly, critiquing videos is the only thing I can do to help people, so if you post like 2 videos against different characters, I can tell you what you should work on, point out your bad habits, suggest some stuff to learn, etc...
It has to be 2 videos though, because 1 video doesn't say much (and you could've just been experimenting in the match, or played differently against the player/character), and 3 videos takes too much time. Hope that I can help once you can upload 2 recent videos of your gameplay, since old videos could have an outdated playstyle so I'd be critiquing stuff that you already fixed. : /
