I noticed in a previous post you mentioned that you studied fundamental skills pretty seriously, what advice can you give about doing those studies? Especially things like perspective and colour theory. How do you ensure that you get meaningful information/practice out of it rather than just muddling through the thing? Alternatively, what resources/books would you recommend to develop those skills?
I guess my best advice when it comes to doing studies is to be comfortable with the feeling of failing - especially with studies. But, and this is important, have a way in which you can check how you failed. One great way is to have a reference photo, say a human figure, and try to draw it without looking at the photo. After your attempt, check it alongside the ref photo and see what you got right, what you didn’t - and then work from there.
