That's Half Life and I have to say it's not your best. The flow is all over the place, the random red streaks look bad and the horizontal line beside the renders face doesn't work. The colour scheme is good as it goes with the render. Seems unfinished to me :/

I like it. The red streak as Irish said doesnt fit. I dont like the big bubbles near the front mostly the huge one on his left arm. It seems to me that you cant really see his body over the effects.
