I saw someone suggest more mutations which boost stats and came of thinking of this suggestion. I'm thinking a heavier model and a lighter model and no not a starved model and an overweight model, more like for example a grey hound for a light model and a St. Bernard for a heavy. An English fullblood and a Shire horse, you get me. I did a couple of quick photo manipulations, destroying Xylax's beautiful line art here.



W/o touching the face I simply tried to add more muscle to the build and at the same time thicker bone structure to provide support. Bigger paws for this build looks good as well. I made some of the shaded areas to appear a bit smaller for the illusion but yeah this is really quick made. Something to add to this model could be excess skin which would be really cool. For stats I was thinking additional strength, maybe even stamina for its similarities to endurance in other games.
Im gonna upload the original art as well to make it easier to compare:



And now the slimmer build down below.



Excuse my bad idea of lion anatomy. This model is basically the opposite to the heavy one. The legs have been made slimmer and longer while the shape of the stomach have gotten a more canine shape. Smaller paws for easy movement and a thinner tail and neck. In dogs I notice that dogs with long legs also have a longer tail, might be a good addition to my model but I didnt think of it while I manipulated it. I dont think of this model as one lacking in muscle but rather having them constructed in another way. Stats for this model could easily be boosted speed, maybe even agility since the light build would be easier to manouver.

I would gladly welcome some anatomy suggestions if you have anything to add!
