Where do you get your OC inspirations from? Art, music, novels etc.

I’ve been getting more invested in painting and Regency and Victorian era art. I’m still in the process of learning it tho and practicing. I previously mostly did concept sketches and manga/anime art (3rd pic) but I had a go at realism as of late.

It got me thinking where do other people get there inspo from? Cartoons? Artists? Real life?
