So I'm toying with the idea of giving avatars several points of customization, since as long as I'm not changing the overall silhouette of the figure, I shouldn't run into too much trouble with avatar clothing. Although I can see a few minor problems that can hopefully be ignored or be fixed later.
Here's the three basic levels of fitness. Extremely muscular, average, and chubby. Since none of the features actually move between the first two, I could give players the option to scrub between the two and find whatever level they're happiest with, but unfortunately that cannot be done with the chubby option.
