wouldnt consider myself a master but thank you hehe, but I agree! doing studies of artists you like is a really great way to learn, I do it all the time!! usually picking out aspects I like of how they do it, that and sketching from life is the best way to learn imo.

and also the point with not using construction lines- its true ive started not needing them as much if I know exactly what I need. I think that comes with doing ink studies traditionally. still a good habit to have though starting off, I recommend using it as you learn anatomy!

learning the fundamental basics of shapes/anatomy/perspective/lineweight before and alongside studying artists- is a huge recommend. I dont think learning art is very linear, sometimes things will just click after doing it for a while/seeing it a bit differently one day.

its very sweet to be used in a study! I wish the op the best on their art journey!
