Crabrawler is made almost entirely of smooth, bulbous shapes layered on top of each other. The lack of musculature is excusable since it's a crustacean, but the limbs and joints don't even look properly-joined, it's like they're just stuck on the surface with glue.
Compare this with crawdaunt's arms, for example, which are clearly socketed into shoulder joints.
Also, from just a kinematic perspective, the fact that they only gave its legs a single joint is going to make it look really weird while it's walking, since the point at which the leg contacts the ground would have to rotate as crabrawler moves forward, due to being unable to change the distance of its knee to its body.
The thing as a whole looks like a balloon animal, a far cry from the animal which inspired it.
