Opening a Patreon is probably a very good idea, and I'm sure you'd get tons of support. Unfortunately, I'm not much of a fan of Patreon myself, so I don't think I'd be one of them. Not because of your art; your art is great. Just because of Patreon itself.
If people are bent on helping, I go to college and work, and that takes a lot of time off my art. It be nice if a bit of support will help me through those times, and hopefully I'm able to provide some promising art stuff if enough support is given.
