Another star sig? I must say, it looks good, except for the starry background. It seems like everyone's doing it, and it doesn't even look that good to be honest. they all look like renders slapped on a background, with a few brush effects. I'll admit this is better than most others, but it still looks odd. The whole nature of the figure goes against the starry background, he's just floating in space. Even though the guy looks like he should be against a wall, or in the middle of a firefight. The last two have really bad/distracting lighting. The gradient in the corner is way too opaque, and seems to be off balance. Something should be there so it's not entirely empty, but it's just too distracting.
:/ I go with most everything Kumquat said, and to add some other things... I feel like there are almost two focals with that text. Also, the render is so dark you almost can only see his eyes. I also feel like there are two light sources, from behind him, and in the top right corner. On the otherhand, the flow is good, and it looks nice. But I'd say it's ok.
Nice signiture, i agree with kumquat...V1 is best IMO. The yellow thing in V2 and V3 SUX. But this IS one of the better star sigs.
