How or where do you get your graphics?

This is partly out of curiosity. I'm in the middle of a project that will use the RTP style, but with custom assets. However, it's been a little difficult finding tilesets and other art (especially enemy art) that would work with the chibi-based RTP style. I see some on Steam and itch.io but not much.

I'm just curious where your art came from for your projects. I'll probably have to create a good but of mine on my own.
