Well these are my first ever 2 sigs my first one: and my second one Iam still pretty noobie so please cc is accepted.
Its better than my first sig ever, PP I wouldn't put glw on your render and try blending him in though. Good for a first though
For a first they are not horrible, probably better then my first attempts. I'd suggest taking a look at a few tutorials to get you started and go from there, lots of info on this site. Keep at it bro.
