Looks ok Kinda bright tbh and the left side of master chief looks odd. the c4d on the bottomright sticks out tbh.
I think Master Chief is too blurred(lol this coming from me) and maybe tone down the sparks a tad, just a tad as if you tone them down too much they wont ahve any effect, I think I like v.2 best because you can see the planet more clearly, otherwise I like it. Keep it up. Oh an also I would try sharpening up master chief.
