the 'hind' leg needs more musculature on the upper leg. and I would make the angle of the heels less straight, in my opinion it looks better with digitigrade legs. the rest doesn't look too bad.

yeah the 'back' leg turned out thinner than i meant ti to be but i didnt fuss much since ti had originally jsut been intended as a crappy sketch anyway lol digitigrade stances look a lot less boring to me than plantigrade, but i'm trying to get away from the lazy legs and feet i used to draw and make them more appealing and less awkward looking, i'll probably work more with this basic leg structure but make it a tad bit more animal-like and of course i need more work on paws, but i've been practicing a little on those already

do that. and keep in mind to make the paws (and occasional hooves; I'm sure there will be some in the future) big enough to be able to bear the full body's weight.

yeah, i need to get a good idea of how everything should be structured to function well and make it looks nice as well
