Welcome to the forum,
mwesten1, or,
Andrew, as you've put down your name

It sure sounds like an interesting project, and you seem to have grasp to ropes in this path. However, in regard to your request, it is unfortunately a fact that in STALKER community -as it is in other gaming communities- there's a shortage of graphical designers. Only a handful around who can possibly manage in-game quality work, and those are currently either very busy up to their necks with their own mods and such, or taking some short breaks.

Still, I would be hopeful that one of them could in fact find himself at the position to be able offer their input soon. In such matters, answers do not come quickly as such works are generally very intensive works and people would like to see that they would
really be able to do and finish the project once they've started. Again, very interesting concept, though.
