Do you have any tips/ advice to improve your art faster?
Depends on the person! But here's what has worked for me.
10 minutes a day at least. Anything. An idea, something you see, a chair, a hand, etc.
References. I don't use them a lot, but I'm currently working on more dynamic poses so I look at real people in videos or example sites and just try to draw them. Tracing or without tracing is fine. If you want to avoid tracing: I'd set up lines and simplify shapes to learn angles and proportions.
More references and videos! I'm a bit busy for this one but I try to review specific things a week. Like watch and reference a video about hands, or the wrinkles of clothes, color theory. Don't hop around often. Drill a single subject for at least a week, and if you're ADHD like me, switch to a different subject for a bit.
DO NOT AVOID SOMETHING HARD. You won't get better if you do. Hiding hands, not drawing full body to avoid drawing feet or shoes - STOP IT. Like, if a pieces is MEANT to be like a headshot or a half pieces, that's fine. But if you're doing it on purpose to avoid hard subjects, you're never going to learn. I always draw hands even when I hate it. If it works for a pose of a hand in a pocket, I still draw wrists and thumb.
Think. Look at real things around you, especially when out and about. It's awkward to stare at people tho, so try to hold them in your mind's eye. Simplify shapes again. Is their jaw round? Is their body large and square? While yes, references again can be found online, what I like is the challenge of making my mind have to think quickly when breaking ideas down.
Timers. Instead of 10 minutes a day at least, I do occasional 1 hour bursts. A timer for 1 minute, 5, 10, 15, etc. How fast can I draw something recognizable? Sometimes we take too long on something and the lines become tight, messy and awkward. Loosen up!
Anyways, I'm flattered you yhink I'm good enough to take advice from! I used to doodle but wasn't very good until I started forcing myself during Lockdown.
Long way to go, but it's all about practice!
