Anatomy? (Patreon)

I will always give the same advice:

My anatomy got better when i started to draw real people. But if you need help for poses there's a software called DESIGNDOLL. You can freely make the model move and change body parts.

It's mostly free but you can purchase it and access a bunch models and poses in their atelier.

EDIT: Don't forget to train and do quickposes daily (if you can). Take 20 minutes of your free time and do 5 poses!
