You could use some bubble C4D's in the top avatar thing. :3 Also the light seems a little off- but not in it's placement. You should darken up the bottom more or lessen the light itself.
And for the bottom, i like what you did, but make it less... pink. Pink just doesn't seem to fit it very well. :3 But good job. I like it.

@Aero: The middle part of the C4D is extremely distracting to her face- which is the focal. Also green and yellow don't quite fit well, with the siggy I think. But I like where you went with this. :3

@Gliscor: yea, I feel that way a lot too. :C When you feel that way, just take a break. Play some video games. Give it a rest for a day or two. Something other than graphics for a little while.
