Since I started to watch more Jojo's Bizarre Adventure a bit more I figured I'd try to do some gesture drawings of poses like in that anime. I didn't drew them after any particular characters or poses but rather used action lines to draw my own.

This is what my practice sketches look like and why I don't post them. I don't even do enough practice sketching because I much more prefer having drawings I can post. I'm wondering if I would even get any better by doing these?
Would it be worth doing this for months and thus not having anything to post in that time?
