This is a discussion on Some of what I used to make within the Horse Artwork forums, part of the Horse Pictures, Videos, Artwork, and Contests category
Those are so stinking cute and I agree that you could totally do these on a custom/commission basis and get a lot of business, but I completely understand about the pressure that comes with doing commissioned work. I also have a full time job and if I have a lot of orders all at once, I tend to stress about getting everything finished in a timely manner. Sometimes even when I only have one order, life gets in the way. It's definitely a balancing act.
These are fantastic! You could definitely sell these if you ever start making them again; I'm sure people would pay you to make some of their horses, me included if I had the cash, haha.
