im no sig atrist, and usally i dont like anything unless its animated (hence mine, home made and proud of it) buti quite like them actually, they dont have that "lets cram in every single picture i can find on the net" look about them. Then again maby a little more background would make em look better but yeah i like em, simple is good (in my view).
only crit as i said before maby add a background so some of the plain white ones. then again like i said im no sig artist.
