I don't think it's convincing that left guy's pose is holding his weight.
I think you should look up references or try it yourself
in that kind of pose your butt is usually lower to the ground I think
and you're usually kind of hunched over with your shoulders forward and arms over your legs ...I think

I dunno, I'm not about to get up and try it to figure it out myself, but I think you got the idea.
...Unless he's supposed to be seated on a to-be-filled-in chair? In which case nevermind

but, yeah, I think that at least his calves need to be longer, while his arms look too long
