The text is great, render is nice, and the colors are good, but the effects seem to chaotic. Try adding color and makeing the guys face (the focal I'm guessing) a little bit sharper maybe, the detail is kind of drowned out by all the color overlays.
V2 looks way better, I like the color more, It stands out more. Your other one was bleak this one is great. Nice job =D It's just the fake light source is kind of distracting yet it helps the piece, so I don't know.
