And don’t be afraid to experiment/go out of your comfort zone.

hmm I would say maybe not to treat the learning process like a race, to give yourself some grace we all learnin

Something I once said is "if we could go back and fix things, then we wouldn't move forward." And I think thats pretty like, philosophical of me.

1. Don't go straight for a good sketch. Make vague blobs to work out the general composition, poses, and so on. Don't worry about anatomy here.
2. Use references! Sites like posemy.art or the Clip Studio Paint models let you customise poses yourself. You can photobash stock photos too!
3. Draw hands. Draw feet. Draw that weird angle. They won't look good at first, but you must practice to learn. Again, use references.
4. You can draw spiral thingies to make foreshortening easier! It does still take practice, but make the loops bigger the closer they are to the camera. Just keep in mind the overall length across the canvas. E.g., a hand that's closer to the camera will be wider and shorter on a 2D axis.

ALWAYS mirror your drawings
