Okay, your getting two critiques because you changed the pose. So, the first pose we are looking down at her based on the perspective that you chose. Also, the pose needs some gesture and the head is too big which contributes to the arms looking too short. I did a quick sketch to show you how you could do this pose, I hope it helps.

Cool work :) A tip I would like to add is to watch out for the "snowman effect", which is basically symmetry on parallel sides. It seems to be most prevalent around the arms and legs, with a bit for the center of the midriff too. To fix it, keep an eye out for the natural rhythms of the human body, as often times they will fall more on an alternating rhythm or curve-against-straight pattern. I think you could also benefit from creating more straight lines/edges overall to make the drawing more dynamic rather than all round shapes. As for anatomy, I would recommend slimming down the neck as usually it's not wider than the head, especially not for women or unless the model is a bodybuilder. The pec area also seems a bit unaligned. I see you have a curve for the torso bending backwards, but the breasts seem more 2D facing the towards center rather than following the structure of the torso and sitting on top of the pecs, which would make them face more towards the left of the page and overlapping. Hope this helps :)
