Yes, lots. Furry art is often considered to be the largest community based art market worth tens of millions per year at a low estimate. Lots of people spend lots of money on furry art .
And that is the issue. It's a huge market that has lots of competition. There are other fiverr artists whom gave spent months with no orders but after I gave them their first few they have gone on to have hundreds of orders.
Ops problem is his art isn't standing out for most on its own. They just need someone to take a leap of faith to get the ball rolling, get them some reviews and show off a bit of portfolio.
