Doom (2016)

You might remember a WIP scene of which I posted a image sometime ago, so here is the finished image. It is this image images3.alphacoders.com/686/68…, made in a minecraft style, using the skin of the Doom Marine I had previously made and his equipment, and a LOT OF PAIN in gimp in order to look like (as close as possible) the atmosphere of the original. 
I would have like to improve a lot of aspect, but I don't have enought skills with gimp and how to improve the image.
