If your goal is to make money, you probably will have to make what people want because no one will buy your stuff if there's no one that wants it. While it might be a niche, it might just not be big enough. It also is worth considering not charging $20 for a character, especially when you make all of your characters work together, because most people will just go get their own artist at how expensive it is. This whole thing is kind of like making platformer games on Steam. The market is small, and it really doesn't make sense as a financial decision. The best thing you can do is probably try to get hired to make a game with a developer who needs your art so that it is original to the game and that you'll probably get paid more. But, if you make art because you enjoy it, keep doing that. It looks good, people just might not have a project that needs that kind of art.
Appreciate your feedback!!!!
My main goal is to share art that captures the feeling of Eastern mythology, but I’ll definitely take your advice about pricing and audience into consideration.
I’ll keep creating what I love, and at the same time, try to make it more accessible for game developers who might need these kinds of characters.
