what immediately comes to mind is that, as much as i like having multiple legs, what doesn't really do anything for me is having multiple arms. well... taur forelegs are "arms" but thats just semantics, you know what i mean: an anthro upper body having 4 (or more) humanoid arms. though i'd have some exceptions for species that have multiple arms like insects.
another one that doesn't really do anything for me is sphinx type layouts with a human face: for me one of the most important parts i would WANT changed is the face
actually, part human part animal forms in general don't really interest me, but having a dog head would be interesting enough at least! i would much rather have a dog head and a human body, than a dog body and a human head! X3
other than that, there's many many funny body shapes and layouts that i do love to think about :3
