A couple recommendations:
1) I'd recommend ditching the intro (or at least making it quieter). It's really loud compared to the rest of the video, and doesn't add much to video itself.
2) The E-perm thing was pretty funny. A bit drawn out though, and I think it'd be funnier if you threw some other effects in there.
3) Try to fix your set-up so we can't see the keys of the keyboard. This isn't a terrible thing, but seeing as the top of your head is cut off too, it would probably be better to angle the camera up a bit.
4) Solve videos in general are kind of boring to most viewers. The only solves most people want to see are world records or solves with really funny reactions. I'd recommend going for creative and original stuff instead of solves most of the time (or doing something interesting with the solves that keeps the viewer watching). It seems like you like editing and comedy; maybe try some kind of editing-intensive skit?
Keep it up though! It sounds like you're enjoying yourself, and that's really the most important thing.
