I agree - I think individuals can have the potential to learn some things faster or take to them easier, but the larger part of improvement in the arts is practice rather than “talent”.
I’ve known people who struggle greatly with 3d visualization, and I personally have difficulty with perspective in 2d art; practice can help to a huge degree, along with some teaching & direction to tackle stuff that may be more fundamentally difficult to wrap one’s head around. “Demystify” is a good term for it.
Having to start learning from scratch as an atomized individual stuck behind tool & material prices, free time, isolation etc. sets makes that process of learning to represent one’s imagination on the medium take so much longer and feel so much more stressful than it should.
It’s actually funny; what you said is completely accurate - so many of the techniques that are artificially by medium, community, initial costs, are really just the same principles applied across mediums. The most recent progress I’ve made in improving my digital 2d technique were from applying painting methods I learned while mini painting
I had so much trouble with illumination, shadow, and reflectivity before trying different mediums and applying techniques both ways. Realism is absolutely fine to pursue, I just wish more people had the time & opportunity to express themselves without sacrifice & worry about precarity and the omnipresent pressure of profit motive 😔
