I don't see why. The goal was to make the shrimp look tough and fast and the crab to look slow and high in defenses, which imo looks like the case.
Also, it makes even more sense since you get the shrimp by having the prevo hold the Red Scarf which boosts coolness, so it's actually pretty fitting that he'd have a cooler more detailed design.
Either way I can/probably will touch the crab up a bit, but I'd rather keep the shrimp a bit above him in coolness as a nod to his Red Scarf.
