The way you took him out makes his neck look bigger than his head. The colors are fairly boring and there isn't much too the sig.
His neck is almost bigger than his head in real life... Also yeah I kinda see the boring colors but it look cool to me. Also there is a lot more in this than it looks like. It has like 9 layers. =)
My sigs have 40-50 layers . Anyways back to topic. The effects are nice but the colour of the render is just contrasted in the middle of a bunch of colours so just add some layer stuff to make it look more like he blends with the colour.
wow... Thats a lot. Also can u PM me ur smudge settings? And yeah looking at it again he is over contrasted but I wanted him to pop more but it is a bit much. So thanks for commenting on all my sigs btw... =)
