YES! You got the reference >:D

I imagine the Stance of the Thistle Seed to be like: One leg straight, toes pointed straight down, other foot hitched into the straight leg's knee. Elbows next to ribs, fingertips pressed against each other in a meditative pose.

I swear I saw it in a Wu Xia thing, but I can't recall the title.

I just tried that one out (without floating as I'm not that advanced XD), does seem like a very wuxia/anime thing to do. I vaguely remember a very similar pose in one of the tai chi forms but the arms were different (both closer in and one was a beak) but it's been a very long time x_x

Yeh nah it takes years of training to float like that lol
