It's a combination of a lithe panda being weird and the lithe animal skins generally having the "Rick and Morty" design issues where they just look like a skinny dude wearing a mascot suit head.
I know it's the most furfag example imaginable, but Beastars is a great example of how to have do skinny animal characters without it looking weird. Like, shit, Beastars even did a non-fat panda and made it look fine, though part of that is probably because Paru's the daughter of the Baki artist and that manga's whole shtick is knowing how to twist natural anatomy in fucked up ways.
