Your gallery is... errrmmmm... epic!
Congratularions! You are really skilled!
I'm a bit jealous you are already in the point where you are making illustrations for your RPG game...
We have a same kind of project, me and a friend, but we're nowhere near you are... May I offer some help if you'd like? I am responsible for anything concerning the languages in our project, so if you have anything in mind, please do drop by my page and leave me a note or a comment, or anything...
Best of wishes and regards!
