Such elegant lines and beautiful, sexy characters! You have a wonderful imagination. Sometimes the foreshortening could use some work, but I think that you have a pretty great grasp of it already! And kudos for doing it in the first place
And a little crit: that pose that you like so much, when the girl almost fully turns her waist back (like the bunny girl) is almost impossible (try it yourself and you'll see XD) and try to be more careful with how the clothing is stretching (on the bunny girl again, the clothing stretches/folds around waist should go in the opposite way)
Ever feel like you're hitting a wall? DON'T stop. TRY harder. Break THROUGH. It's WORTH it.
