Eh, it's okay. Can't really tell what's surrounding him, and I'm not a huge fan of the coloring. Font could be better, too.
Ok. It didn't turn out as i hoped it would. The background is supposed to be a bunch of men fighting and then this superior dude comes up to rape them all and hes got like electricity comin off his arms.
throw down a vibrant pink or any other vibrant color...throw it on multiply or hard light, and on like 8-15% opacity...use some photo filters, gradient maps. the subtle changes show in the end. trust me [:
reaper's right ... Needs more colours than the dull blue/white =p The render seems either overlightened or too sharp ... (especially the neck area) I also noticed this in another sig made with the same render, so it could be the render too :/
