the sky could use some more caracter, and I think the wide open water doesn't seem to fit in the composition yet. Also the terrain and the castle are fighting to be the vocal point and the size of the ship seems too large in comparison to the size of the castle. also the ship could maybe be placed somewhere else or maybe even left away all together. Also the sky and lighting could be a bit more 232% less then. Just a few things to possibly fiddle with :)
