Do you use reference? Keep lots of reference on your second monitor, check out 3d.sk, art books with female form or just an anatomy book.
Like mentioned before, first do the proportions and relations between limbs.
Also try relaxing her, she looks really tense in this half squad, upper back exercise pose.
It’s a girl, girls are soft. The hip bone and ribs showing that much suggest anorexia or something like that. The knees are really really hard, like the bone is sticking out, check the masses of the shoulder, it actually looks like there’s a part missing there. The neck looks ok, but don’t over do the neck muscles. Girls are subtle and soft 
and as mentioned before, focuss on the sculpt right now and rendering later haha 


all that work for nothing. I need to get myself in the habit of using layers too.

I totally agree with you hopefully it works visa versa too Ive learnt lots about muscles bones etc from this excercise hopefully when i draw again ill have a better understanding of what i am drawing.
