This won't happen for a while, but for the future I have a small idea.
I am going to be increasing my prices after this batch of commissions is fully complete, mostly because I cannot take a lot of them while I'm in college. So, as another option for payment, I want to start doing a sort of trade. I don't mean art exactly, but I'm going to create a list of things I'm interested in/want and do specific art for them.
So, for example, I might say I want such and such game and I'll do a full flat color commission for it, or something along those lines. I want to do this so that people who maybe cannot afford to get art but really want to get something done or have things to get rid of can still purchase art in a way.
Again, this isn't going to be for a while due to my commission list at the moment, but I'd like to start it up in the future!
