It's been a long long while since i last posted a sig here. But been away for graphics for a long time and i'm back now and i see not many new things has come in the Download section of this site since i last came here. Here is my latest sig Please CnC
The border is a tad bright, I think a plain black border would have been fine. I like everything else. The lighting is a bit off, since your light source is on the bottom and his legs have an intense light coming from the left side. The soft brush dots near the board could be a bit better (slightly less of them, a bit more direction and a bit more variation in size). And finally, I think the primary text could have been a bit thicker/different font. Looks a tad jaggy.
Even i learnt something from this post.. I will keep light sources in mind for my sigs in future too haha
