Its in black and white for a reason btw everyone. lol.

C&C?

Hiya, looks nice, the squiggly render parts look very sharp, I recommend a little blending, perhaps brush over or erase the edges slight, a recoomendation for Photoshop users would be to make a selection with the marquee tool, and right click, choose feather, use around 5-10 pixels and then position it nearby an edge and hit delete, do this to your tastes, will help with blending, hope that helps.

Apart from that, looks good, I really like the background parts on the left side, you use gradient tool?
