i think overall the first is very good! but the thing that seems off is the front legs are too curved. they need to be straight of ever so slightly bend in the way their joints move. the tail i think is alright, but if you want it more realistic maybe make it a bit pointier. for the second the arm needs to be longer, the outstretched one. the tail should be thinner at the bottom, the belly straighter, and the hind legs more... shaped, if u know what i mean. theres something wrong with the other front legs paw that i cant explain but yeah
ik this was old but yeah
