The last one is kinda weird, the way the hand is holding the bottle and how both arms connect to the body, but really cool stuff indeed. Good luck with the animation if you ever get to make it :)
Yea i noticed that too when i was done with it, the left hand should've been lower on the body. I also did a mistake with the flower in the middle, the top left leaf should've been more squared like the rest of the leaves. The knees on most of the flowers except the top one looks quite bad.
