The render is blended too hard. At first I didn't know what it was till I looked closer. The right side's colors look very low quality, and the canvas size is too small as well. The lighting to the top right overpowers the render, as you should still see a little bit of the edge of the helmet. The proper lighting should be behind, as it looks like Navi from Zelda floating above the Soldier's head. Nice concept though, just keep practicing.
