needs soom hooks on the wall with tack on them
needs a place for feed for the horse (not just water).. .and even though I see where you're comming from with the placement of the water throughs, I'd probably place them all nice and even like a proper place well cared for
where do you get your elements, do you draw them yourself?
oh and more shadow on the hey and crates - they are stacked high
