Sleipnir sketch

This is such a nice sketch. Horses are difficult enough to draw, nevermind creating a beast like Odin's horse, Sleipnir! What caught my attention were those legs - I like how you seem to have captured two different running poses, which seems quite fitting. All the legs seem to match up to their counterparts appropriately and I feel like I could isolate two separate pairs of horse-limbs and have two functioning sketches (if that makes sense?) I'd love to see this finished a fleshed out more.
