For the most part, its a decent app. I dont love it, but I dont hate it either.
Like most of the reviewers this app really needs an undo command. Im surprised this is not an option.
Also, it does take a bit to get used to the controls. Even when you get accustomed to the controls, be careful to pay close attention to which body part you are moving. I found on occasions that somehow I inadvertently moved another body part without noticing.
This is due to the controls. If you move your fingers too far up or down when posing, you may have accidentally selected another body part without knowing.
For this I would suggest that the developer create an option that the selected body part have some sort of indication/highlight to let the user know which body part is in use.
