Holy shit your current sig is huge, Your new one is alright. Doesn't look like you did too much too it.
Well, seems really basic :S like the the render or pic or wtv lol and beside theres the same in black without any great details and such lol :S
This is actually very nice for your 2nd sig. chris, work on using brushes now and effects(lighting, gradient maps, opacity, filters, etc.)
