Hello there! Great job here! However, the proportions look a bit off. Besides that, the position of the hand makes it look like it's broken. The legs were also too short, or perhaps the fact that the character has a very large bust makes the legs look smaller in comparison. The feet don't feel like they're properly planted on the ground either. :) Making sure your characters are firmly standing on the ground is crucial to prevent them from looking like they're floating. Hope this helps!
maybe block the hand and feet as simple shapes first, then lower the body center a little so the pose feels planted before cleaning the linework
