Hm. You'll have to understand if I can only offer a few points to consider; I only recently got past the 'sucky player' level of skill. That said, I see the following:
Expand your vision: Almost every time Snake did his u-smash/mortar, he either managed a positive outcome (hitting you or forcing a block which he then grabs you out of), or a neutral one (You block but aren't punished, or you're forced back slightly). At one point you dodged into a mortar round. Expanding your vision to see the whole fight, not just Ike, may help here.
Risky aerial Quick-Draws: ...At least, I THINK they are. You often edgegrab, jump, and side-B from it right into your adjacent enemy. Is this really a safe idea? I don't understand why you're doing it so often... can you please explain? I would think this could go very badly for you if they block it, but I might be wrong.
Also, on a more positive note... you do seem to have a solid grasp of Ike's aerials, which is pretty darn important.
