Yeah. It's pretty good, especially for a first sig. I'm guessing that you have yet to play around with all the effects and brushes. Keep doing what you're doing =D
Gah, Sephy! Cut off Cloud's and Sephiroth's hair at the top. >_< It looks really weird like that. After that, you'll be fine. I don't favor that font too much, though.
I tired to fix the hair put it didn't work. So I'm going to fix it later. It had a bigger problem with random pixels every where. So I tried to fix that, And when I tried to fix that I got the rouge pixels in there hair -.-''
