DYNAMIC POSES tutorial

These are great, but one bit of constructive criticism from someone who has breasts irl: the female poses need to have lift when her arms are up. When a woman lifts her arms, her breasts lift in correspondence. The way you have the breasts drawn right now makes them look more like the woman in question may be in her 60s or older - specifically with the sitting pose and the standing one where her hand is in her hair. Larger breasts will have weight to keep them down, but they still lift when the arms go up. Other than that, these are great references.
