I'd like to recommend an app to make taking pictures of your art easier, if that's allowed on here. I use CamScanner a lot on my phone. It's free and really great for greyscale/ black and white images, although I've gotten good results with color too. BTW I'm not affiliated with them in any way :)
Regarding your drawings: I can really sense the movement in the poses. Good job! I'd like to see some weight added to the movement. Include the feet from now on and try to show grounding and balance (in standing poses anyway). The challenge will be avoiding stiffness.
I tried it back in 2012 when it first came out so I imagine some new features have been added lol. Maybe I should check out what's changed!
