I was referring to his topic which is pretty awesome. As for the sig... I would suggest making the render sharper and the background more blurry so that the focus is on the render. But Iuno.
I'm still not happy with it but I'm tired of working on it so I guess it's done. Made completely with the 12 pixel stipple brush and the 1 pixel pencil tool with some smudging in some places. How can I improve for future pictures?
