It's a halfling castle! :o No, seriously.. You got perspectives totally screwed up. Even that wall turns weirdly.. It looks like the ground would be going up but then the water would flood.. And shouldn't the water be bit lower in that thing anyways? It might get into the castle. Got to admit though that I love your choice of colors. Just learn to fix small things like making the things more detailed like using chains instead of strings. Try drawing it on paper before actually pixelling it next time. :) Oh.. And about that water.. It's really pretty but it looks more like a carpet.
