Looks great, now if you answer one thing I'll be happy as a clam, I know this is the contribution forumn but I have to double check. We can have these, no restrictions (besides may be your name in credits for makeing it).

EDIT:
Sorry I lied a couple more questions, How did you make these textures? I try not only to recieve this type of detail in my games but to understand how to manufacture it myself, so can you tell me how you made it or direct me to someone who has?

One last question: How do I use the .rar files/ how do I convert them to a usable type (aka .wad or .bmp or something)
