I just finished a huge commission, and now I'm back. (: I'll be taking 2 slots per month of simple requests (a "simple request" would be a full-body, full-colored character with simple background). Depending on what you want, you may take up one slot, both slots, or 8 slots (last commission was TOO awesomely huge). Each slot will have about a 2 week turnaround. I have never missed a deadline, and I don't intend to ever start to do so.
These do not have to be WoW-specific commissions. They can be anything!
