Alittle too dark, else it looks really nice.
The render looks nice, i like the splatter effect. As with the rest of the sig, too dark, lighten it up a bit. His head looks a bit weird. The background is way too dark, imo. Almost completly black. Lighten it up many places. Maybe change the background to dark grey, instead of black. Text looks quite nice, well placed. Fits good aswell.
