I will say that I like all the details you have on your character, such as the jewellery on the necklace, and it's a nice colour icey blue colour scheme ...

... but I wanted to mention that the pose is really awkward. You've twisted her shoulders around to face the viewer ... but by doing so the arm on the floor is brought further back. Since it's also off to the side of her body and bent, her arm isn't supporting her and she would topple. This is why one-armed floor press exercises are difficult!

I admire that you're trying to be adventurous with poses, but I find it's very distracting to the rest of the pic when they don't work.
