I don’t know what your stance on AI is, but it may do to have assets generated with AI as initial placeholders if you are having trouble locating an artist. The way I see it, you’re creating a product/content, not art (or, put another way, the art is in the dev process). Where I have time, I create the art assets myself, given that AI is remarkably inconsistent when it comes to style (I don’t have time to train an AI on my specific art style).
Of course, if no AI is a hard no stance for you, I’d recommend grabbing assets from anywhere you can. The latest game I’m working on for 1G1W #5 uses assets from RPG maker for instance.
Still a good game though, don’t beat yourself up too bad, lol. The progression of your games is showing, and it’s an upward trend.
