Pros:

+Good quality.
+Moves flawlessly.
+Fits Bill's character.
+Ported into Left 4 Dead.

Cons:

-Shirt seems a little too clean.

Conclusion:

This is a great look for Bill that I really enjoyed. The quality for this mod is not the best, but really darn good. I really like the texture for the arms. The shirt, although, seems really clean, almost too clean. It looks strange in the dark, dirty atmosphere of Left 4 Dead. Once again, this is a great mod and I plan to use more mods by you.
