The way the suit, skin, green, and purple from the flare work off each other is great. I also like the bit with his arm. But as it stands, it's only really nice when you just glance at it. Once you start to look at it, the background is lacking and the light source is like 2/3 of the tag, which isn't a good thing. If you had an actual developed background, it could be a solid piece.
Right now though, it's extremely average at best as there's just not much to it. Simplicity is one thing, bright white light source taking up most of the tag is another. It comes off as a cheap effect and washes out actually good effects.
