not bad.. work on the text which is always the hardest part to work on..also, dont blend the bottom of the render
Its not great...its ok....need a bigger render, to blend, and better text. try getting sum r06_ (grunge brushes).....at DA..or wherever.
The sig is great, i like the rendering, font, and color.. however, the ava seems a bit too big , maybe if you shrink it a little, the pic will be better looking, just an opinion
