Hey there!
First of all, you’ve got an amazing art style so I immediately followed you 
Second thing, and I’m saying this from the “artist” point of view since I’m also one, you shouldn’t really look at this episode community, here people are amazing and everything but just a few would actually commission something here, they offer many free covers, scenes,… (So you don’t really have many people looking for paid art)
You should dive in the Instagram community, it’s chaotic no doubts, but there you have a way wider “market” on which you can share your art, and many people willing to pay 
Maybe it’s because I’m an artist myself that I’m saying this, but I think that art should not be free, it takes hours of your time, focus and creativity, so I think that there should be at least a lil reward, obviously free art is amazing because you don’t have to spend a cent.
I have cheap commissions but you should decide your prices basing them on which consideration you have of your art. You spend 15 hours on a piece? You do many details? You create even your own backgrounds?
Let them pay more.
You can start from lower prices at first but then higher them judging how much is worth your art, and just looking at it, believe me, it is worth it
