Uh, the model and texture credit should be for Tripwire Entertainment. Don't put the game title on the credit. :D Always put the name of the developer who made the model and texture.
Now, a comment for your skin and the animations:
The drawing animations is... BAD, I suppose. Also the sound of it seems like it was being cut halfway. The firing animations seem to be exaggerated (at least for me). The reloading animations is pretty damn nice. Good choice on the sounds, by the way. The texture is waaaaaaaaaaaaaaaaaaaaaaay too shiny.
You need to fix the sleeve texture error (the one with the violet and black, as what was shown on the video) and maybe the draw animations of it.
