It looks good I'll give you that, the pose is nice, the armor/gun itself too, with nice attention to the lighting and decent value range. I think you could have saved a hell of a lot of time using bigger brush strokes...I see lots of little soft lines shading smooth surfaces and it sort of implies you worried about messing up so took it safe and slow. The anatomy looks alright to me, bit tricky to tell what's going on the with far arm.
