I give it a 5/10 it's good for starters. Perhaps making the size a tad smaller. Maybe try to colour the bg to a few shades close to the renders colours to they match. Then possibly do some feather or brush around the render to blend it with the bg more so it doesn't stick out.
I'll give it a 7.5/10 The render could use some blending. btw- don't post unless you're going to rate. (that's what someone told me)
omg1!! ub3rn3s$ Who dosen't like bannas? exactly lol dont really know how i can rate them though 8/10 would be better with tophats better?
Brewha, Nice sig. Love the text nice job on it Tech border thing dont fit with the render though 9/10
wow, thats a great sig. 10/10 Everything is perfect. Text fits, great lighting, and awesome useage of the render with the bg.
