its looks ok, but its a bit odd that the sholder isnt moving. despite the fact that this dude doesnt have the mid part of the arm, the sholder should move accordingly to the movment of the hand, for exemple if the dude moves his hand up the sholder shuold spin up too.
its a bit hard to understend at the beginning what parts of the body should move and how but its simply takes a basic understanding of how your body moves, look at your hand as a reference and try to imitate its movement, this game doesnt ment to be realistic so remeber that its just a refrence and you can, as long as you keeps the basic movement correct, do what ever animation you whant (take tom’s mammoth animation as exemple).
i hope you will find this helpfull, and good luck in future animations
