As most people will know, Crocodiles and Alligators are two of the most popular species in the game. Although, they're underwhelming, with diamonds being the same size as every other male with no visible difference. I feel that they need an overhaul, with actual differences in length based on the trophy score.
And with this rework, why not add a Great One? A Great One alligator could be an amazing addition to the game, bringing in new players and old players who may have stopped playing.
I propose these skins as base skins, Although you could add and remove as you see fit.
