Haha, that "monotone-ness" was a pain in the ass to get. It took me at least seven layers of gradient maps to get that.
i like the streak lines in the back but not the one in the front i feel it just makes it look more dull but there needs to be a lil more going on
I believe a hue/saturation layer w/ colorize checked could get the same effect in one. As for the sig it's nothing special. Wave is okay but other than that it's pretty blah.
