The lossy .jpg images are a major turn-off, but the overall look of the drawings isn't that bad. The style is cute, and fairly consistent between avatar and signature.
Clearly not much effort was put into creating something of your own with this, but that's of course not obligatory. And the complete lack of text or coding in the signature is fine since the image looks all right on its own.
The avatar feels a bit lacking; the given space is hardly used to its full extent, and the wide image with lots of empty space makes the icon look rather small; you almost have to squint with your eyes to see the image properly.
Though art style-wise I like it, it's moderately cute and the theme is fairly consistent. But I'm afraid that doesn't do a good enough job to carry the entire theme.
