Friend asked me to draw him a my little pony in ms paint since I owed him a favor. Don't really have much experience drawing pony and my anatomy in general is pretty weak. My question is how I should make the thigh highlighted in red look in relation to the other. Would it be more compressed and "fatter" or should it be extended out more? Bonus: any tips on how to draw pelvic region would be greatly appreciated as well.
