well, it looks nice, but...
a. i think the text disappears too quickly. Personally I had to wait for it to go around again in order to read everything.
b. I think the pictures actually blend in too much. Make em stand out a tiny bit more.
c. When the pictures show there really isnt anything there on the left, like any brushing, but at the same time if there was I guess it would mess with the text. If you can find a way to have some brushing or anything there, go for it.
Other then that, (and there are plently of elements other then those), the sig is very nice. Plus, its nice to see that youre making it because youre a very artistic person, and that also comes off in your sig. Keep it up buddy.
