@ambiirae I would look into the Art Renewal Center, they have a map of Ateliers that focus on classical methods to see if their are any near you. https://www.artrenewal.org/pages/ateliermap.php
There is the Jeff Watts atelier in California that offers online classes starting at $100/month which is a lot cheaper than art school.
Look up Baruge plates on Google and youtube, they are helpful for learning how to draw at a high level quickly though they are tedious.
I studied graphic design and just paid my loans off a few months ago. Art school is way to expensive and most don't teach well in my opinion and should be avoided especially if you already have student debt. Try and find alternative routes to learning art.
