Quoted for truth, but it's understandable if you can't find a good opponent to play against. You can just use a digital camera to record the match; the quality isn't too bad, in my opinion.
I watched the match; I'm not really sure what to think of your Ike, since Wi-Fi tells so little. I noticed how in the beginning of the match, you tried a lot of jab -> FTilt; you should only try to do "fancy" stuff like jab -> UTilt/BAir/etc. when your opponent is at a middle or high %, since at low % you want to focus on bringing them into killing range with guaranteed and easy damage; the jab combo fits that criteria, not jab -> FTilt. Jab (cancel) -> jab combo works very well for this, I would recommend using either that or the not-as-guaranteed jab -> kick (cancel) -> jab combo.
There were also times where you just threw out Eruption at high %, but not so high that your opponent would die from it. In my opinion, Eruption is a "what-the-heck" move, in that you'll only get it off if your opponent is not expecting it. This means that when you do use it, you want it to count; if you are following this guideline, you should only use Eruption when it will land you a kill or if you're coming back and you want to protect yourself from an overly-aggressive edgeguarder. There were times when it seemed like you just threw out Eruption hoping that your opponent would run into it; try to bait people into running into it, rather than throwing it out randomly.
Last thing: I know it's over Wi-fi so the connection plays a huge role in this, but your DI was very bad at times. At any moment you realize you've left yourself open, you should predict that your opponent will punish you and hold a direction to DI in. There were some times when it looked like you weren't DI'ing at all.
