I like it, the lighting on his face gives it a good effect but I think its a bit too dark on the right hand side so it looks off balance over-all tho it looks nice :3
Nice affects. The sig itself though is lacking in depth and color. These two things also take away from the focal point. The whole sig kinda just looks like a bunch of dark blue with a random white light in the center. Try working on depth, as well as adding a bit more color. Also, the stock used looks like it's VERY bad quality, I don't know if it's something you did, or the stock was just bad, but you may want to fix that.
Would much rather you get a better quality stock next time. Or maybe you did something with the effects to make it look like that? Either way, you should fix that. lol Otherwise, the effects could use some depth work. The fact the lighting isn't behind the guy or out-of-reach makes the light reflection on the stock seem pointless. Especially since the effects are so much better in quality compared to the stock. I think your only MAJOR problem is the stock. Everything else would be fine otherwise.
