I believe that the skin looks nice and simple and I believe that you made the pattern with the photoshop filter, i did that too for one of my skins. As far as the looks go, its pretty good and i do think that this should be implemented in the game. If you want, you can also check out some of my skins and tell me what you think of them.

Myself, I would get my wallet and buy a factory new of the blue, green and purple ones.

what would I had ? I think you can add few very small sploshes of blood at the botom near the cannon, make the trigger look like a raptor claw, and make the exterior of the magazine look also like a raptor claw, remplace the neon like aspect around the thing that block the blow back part whene there is no more ammos in the clip by a shiny dark gray or black aspect, and that's purely a personal preferance, replace the lines on the sight by simple glowing points, recovering the neon like aspect of the part I talked about earlyer.
