Dude both are awesome, but I have to vote for Timmeh...the characters face and back ground just match perfectly. Though I am no expert in judging sigs, Timmeh's seems to blend perfectly for me. Sharingan..your is awesome as well its just that the only Yellow hair bothers me because it kinda stands out too much. still great job both!
i'll have to go with Timmeh on this one:. Nice blending and structure...loves the line effects on the left...Shar's is good too but a little too bright for my taste...
