i can see the perspective you were going for and it work!
the top left shoulder line should be crossing thru where her top right shoulder line would be heading.
her bottom wrist line should be less visable and angled more.
at the position of her shirt that's dangling off the left, there maybe should be a rounded "back" of the t-top that would fall behind the front.
the left side of her panties/theig should be angled more.
very impressive knowledge of form especially for this being a no reference. ..it pays to draw the body over and over and over.
