This was one of my older ones..










Feel free to criticize me as hard as you want. I need much improvement

nice i like them and i don't know about sigs
the last one is really my favorite with that eye thingy , only i can't seem to figure out what that blue thingy is doing there, but overall it's a nice one

The spiderman one could be better if the background had more dept and color to it. I don't really like the other ones. Keep working and you'll get better!

The blue thingy in the corner is sasuke holding chidori v_V I couldn't really render is very well, Chidori is EXTREMELY had to render.

keep practicing too, a good sig doesnt need to have a superr different weird looking text, A simple text works best

They look pretty good. The brushing could use a bit of work as could the use of renders. I think you duplicate the renders to many times, If you are looking for a motion effect try using "Motion blur" so it blends in a bit better. Thats the effect i believe you were trying to go for on the last sig.
