Funny, but...

Okay. The classical music is perfect for the type of comedy (IE: slow-motion nutshot), and this type of comedy is very appealing. However, there are things that you need to work on.

First, you need to add a LOT more frames. As it is, this isn't slow-motion, it's just really choppy. There also seems to be some kind of weird skipping. Is it just my Flash player, or is it the Flash itself?

Second, make sure the music is absolutely synchronous with the animation.

Third, improve the character's movement. This may be a matter of practice, or just more effort. As it is now, he doesn't move much.

Finally (and this is the one I feel the worst about criticizing), keep working on your artwork. Most people, if not all, do tend to judge a book by its cover, as it were.

Start by drawing freehand. Even if you suck at drawing and even if it's just a bunch of rough circles, it's still better than auto-generated lines and shapes (did you make them in Paint?). Then, make the room look more like a room. Remove the purple, add a couch and a lamp or something, and a colour that looks more like it could be painted on a wall.

This has potential, but it's not done yet.

You're gonna need more frames than that.

The worst problem with this is that the frame count is WAY too low. When it's like this, it's kind of hard to make sense of it because so much is missing. Try to fix the bizarre timing too. When the first ball was kicked, it moved at a snail's pace, then hit the second ball, which flew off in no time at all. Also, it looks like you converted it somehow - the quality is really low. Keep practicing, you'll get better.

Meh.

The visual quality was quite bad and during the kick his foot changed size.
Also, I think you should speed up your animations slightly.

Hm.

Try to make it smaller in size, faster in animation and less 'shaky' :) Have fun making more!
