They are pretty good for being away so long... we miss you the tekken one with wesly snipes ) looks appealing
First one would probably look better with color although i'm sure you probably already tried and decided it didn't. I like the coloring in the second one except for the part where half of the sig is black. Whatever the white effect is that looks like a somewhat scattered brush it would probably look better if it flowed kind of in a U shape with the left side alot longer with the c4d effects from the right of the person, or you could even make it follow the arm.
