Okay I actually tried, and, shocker, I was able to do these two poses. My spine actually allowed me to do 2 poses that are from a non-realistic drawing. Wow, shocker!
Did you just misgender me? Wow. again, this is actually true to how a spine can move, the pose is 100% do-able by any semi-athletic person, the only real problem I can see for the piece is the boob's gravity, and even then, it isn't THAT big of a problem.
Actually, this art is much better than my art, I can admit that because I'm not a narcissist and I know my art is not the greatest, either way, I like what I do, and I think hating on art for the style of it, aswell as 1 minor mistake, which could even just be classified as stylization since they're in a way that's overdramatic.
