I love the pallette you have used

same as the texture on the bridge (i think it's a bridge, or castlewall or.. ) anyway. i do think that the shading isn't right on the bridge. since you have mirrored it. if you look at the shading of it it looks like the sun must be in the exact middle, and it isn't. I don't know if this was on purpose.
I do think the sun has a very original design, please finish !:P
