Ronyle's skins just HAVE to be great. You make many of them, and each is of high quality. Also IMO best renders on whole UnrealSoftware.de. Keep up with the good work!
Good render, the shape of the weapon looks good unlikely the shading. You CAN make shadings on black weapons, just make some lighter colours on a pallet, don't make them look like grey but slightly lighter than black. Than define the area's that could be made a little lighter like on top of the stock and base model. Because the drop picture is smaller and thus not so easily to make light effects on it actually looks quite okay.
