I really like the body type you gave Dash. A small and thin really add with her love of speed. Given her character, I would have been tempted to make her taller, since tomboy often have a more masculine body type, but I think your idea is better and really add something to the character. I may reuse this idea in my fic, if you're ok with it.



However, it's a bit strange for me that Rarity is the second smallest pony. She has some characteristic of a femme fatale in the show, so I would have image a slender pony a bit taller than average. Once again, your version can give a nice contrast, but I'm not sure it is needed in the case of Rarity.



Anyway, it is a really great art, and it started my thought about ponies body type. Thank you very much for it!
