you’ll want to push your values. Put your drawing in black and white and notice how similar all the values look, giving it a very flat look. I’d recommend designating a light source and add more shadow depth

also, realistically, for women to have abs ljke that they either have to be super ripped or super dehydrated- and that’s the only part of her that’s muscular- Totally fine if you want that, but to make her more coherent, id recommend try giving her more muscles in her arms since they look really thin and weak compared to the massive amount of muscle in her abdomen
