About the way you draw breasts: the center folds of the breasts don't go up that high. They only go about halfway up the breast, unless the breasts are pressed against her chest or pressed together (in which case they create cleavage). And the outside curve of the breast should be like an "S" where the bottom part is rounded outward and the top part curves in and tucks into the armpit.
Aside from that, I really like this. Great colors and beautiful face. Liking the red nose.
