Added a few details in the back and one on the bottom so that the p90 fits more to the rest of the progressiv stuff.

Again changed the surface of the weapon a bit, so it won't look to plain. Also adjusted the white in the white parts a bit.

Just made the black parts a bit brighter and the white parts are bit darker ... so its not glooming that much.

Uploaded the wrong file without alpha channel. So had to reload the correct files.
