Your avatar is very choppy. Your sig, I'm kind of confused... All you did was crop a picture and add text. The text doesn't even go with the picture either. I suggest you look up some tutorials on how to make real sigs, avatars, etc.
Well the signature isn't really a piece of work... it's just a water lily with intelligence spelt wrong on it.
The avatar is... well it's a good idea that's only underdeveloped. Keep working on the avatar, but get a new idea for the signature. If you really want to impress people, use filters. Make your own pictures instead of just copy/pasting pictures and putting text on it.
