7/10 looks kinda kool, text brings it down some...and something dont fit...not sure on what 8/10 nice lighting i guess...the line across the face dont look right
T.i.piO 5/10 6/10 I'm just not a big fan of sigs with c4d renders in them. Looks cool but it's not amazing.
i like that sig ^^ it has action in it...some are just plain, or the render is just sitting...but yours is in action. 8/10 (rate the sig i'm using )
kinda too big, leaves a huge plain space... work on the text, don't use pixel font like that... render is sorta small... 6/10
first one... 6/10... not that great of a bg... second, 7.5/10, i like the overall feel, but text and border are off.
