I dropped out of art school, so I'm no expert, but I think it would fit either place.
I'm sorry to hear about your imposter syndrome, because I think this is really cool. It's bold and colorful without being overwhelming, there's so much action and emotion in your line work! Tbqh, it feels to me like part of a series, it makes me want a dozen more, so I hope you had fun with it and decide you want to keep going.
