I see you've been getting a lot better with your female anatomy. I also rather enjoy how you do your less muscular character. I believe the correct term is "ectomorphic"? I do feel you might have hyper extended the leg of the character doing the hand stand but this is after all a sketch.
I love it all dage great job and u inspire me alot but may i suggest a few things? Something bout the leg sticking out on the guy standing ob his hand bothers me but i love the concept of it, i really like the ninja girl but i kinda like her attack position compared to her standard position. Dont get me wrong i really love it all and u inspire me and i was wodering if i could maybe get help
