¯\_(ツ)_/¯

earth ponies are naturally stocky, with tough hooves covered only partially by their fetlocks. very strong tails which they can use to sweep or whack things. their snouts dont curve like other ponies

pegasi are typically lithe, with hollow bones. their coats are thicker than other ponies, designed to keep them warm at high altitudes. their hooves are covered by a thin layer of velvet to keep them protected during flying. they also have excellent hearing! hence their longer ears

unicorns are considered graceful and beautiful. they have cloven hooves, and long fetlocks. their hair tends to be wavy. their have long tails that serve only for aesthetics. they have shorter, more smooth snouts. they also, regardless of gender, have beards!

each of the pony races have a "heart mark" on their back left hoof, which first appears as a simple heart at birth, and later changes to match their cutie mark more closely

applejack; her tail is kept short to avoid it getting in the way of work. the green in her mane comes from her pear blood. her cutie mark is meant to look like a quilt piece. similarly, her handkerchief is filled with references to her family and loved ones. lastly, her hat has stitching of a gem and a heart

fluttershy; i gave her a very deer like appearance, and markings on her wings to resemble birds. her ears are a bit longer, to resemble a bunny! she has small wings that are really only good for gliding. shes part unicorn (idk i just thought itd be cute if one of her parents was a unicorn) she used to keep her mane long but rarity was horrified by how many twigs and leaves she picked up, so she convinced shy to cut it. she quite likes it!

pinkie pie; PIEBALD PINKIE. gave her blue stripes to bring cotton candy to mind. her design is very asymmetrical which just feels very pinkie! even her eyes, they heterochromatic. the left being blue, and the right yellow. she keeps her hair up most of the time so it doesnt get in her way (during baking, party planning, baby sitting, ect) ALSO FAT PINKIE RIGHTS

rainbow dash; i wanted her coat to resemble the sky, hence the markings on her legs. her mane and tail are kept short to keep them out of her way. she is rarely seen without googles, as she wears them when she flys to protect her eyes

rarity; FAT RARITY RIGHTS. ahem. her eyes are green (small play on being green with envy) and she has poor eyesight, so she wears her glasses regularly. honestly, hers is pretty simple but i wanted it to be elegant, and beautiful
