1000 Poses challenge. (and others)

[Arthurv]

Hi guys.
So here's the deal, I've been struggling with gestures and anatomy lately. So I've started a self-imposed challenge of drawing 1000 human poses. Yeah, that's right. So I go into this website, http://www.quickposes.com and do two 60-second/drawing challenges a day, that's about 40 poses a day. As a bonus, it works towards a certificate. This thread is actually so you guys can tell us what kind of drawings you had the most trouble with, and what you did to get through that difficulty! (Also, if you're currently in an art challenge, tell us what it is and how it's helping you!)
These are some of the poses I drew now that I'm about 60 poses into the challenge:

Great idea! I would also recommend, however, doing some longer anatomy studies and figure drawings and try to get everything as correct as you can. If you do this, you will learn more in one drawing than a ton of short gestures. The reason for this is because gesture drawings aren't often focused on form, perspective, and anatomy, so they only help with one aspect of figure drawing: the energy.

Good luck!
