THe line is weird. Get rid of it. It kills the flow and really draws your eye out of the sig.
The blending on this is horrible. You just lightly painted white with a soft brush and called it quits. Not good enough, it looks very sloppy and dosn't blend well in any way.
The text is kind of brutal. I like the font but there text in two seperate places? Not good. ON collab sigs it's easiy to just not put name son sigs and just sue the title like "sprite".
THe c4d isn't bad though nice placement and coloring is decent.
