It looks great! only thing I can say is it looks a little stiff, I feel you could improve this by paying attention to and studying how forms "squash" and are pulled down by gravity. Also drawing circles for each of the joints will hold back your art and contribute to this stiffness. So I would work on getting out of the habit of doing it.
didn't say this in the first comment but I have noticed the stiffness as well, I will definitely be trying to work on fixing that as well! Thank you so much for your advice :)
