I really dont like the lightning effects, they are too rough and random, and detract from the other effects due to them not blending in in any way. Text isnt very good, it is hard to see, and the font isnt really that great, youve used similar ones quite a bit in the past, and Ive never liked the style.(large spaces between letters) There seems to be just a bit too much contrast between the dark of the face and the white of the clothing, it obscures his face (which is basically the focal) which sort of diminishes the sig as a whole to me.
Lighting is nice, text not so nice :/. The effects take away from the text and the effects don't seem to blended, however thats not the end of the world.
