A simple ToS

I will start to work once I received your payment. On my side, I will provide a sketch for confirmation before I color it, if you don’t like it, you may request edits or demand refund. I will try my best to finish your commission in a month, if I cannot meet the deadline I will notify you. You may demand refund too if it is overdue.

The art is only for personal use, such as using it as avatar or banner. Using it for commercial purpose without notifying me first is NOT allowed.
