Im not very fond of the first render and I don't think the BG fits well with it.
I like the second sig but it could use more work on the BG. Maybe a bit more brushing. It just looks a bit plain. Font choice isn't great but readable. Love the render though
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
