Hey Albert. I like the middle one. But still you have to lock the design for your buildings rather than just square shapes. Also, the ship looks very cartoony. Looks like orgami ship which destroys the overall scale of the painting. First one feels that top part of the painting is disconnected with the foreground, Use more overlaps with foreground and middleground elements to create more depth of field. Third one isn't working in terms of the value. But I like the idea a lot. Just do other composition but same idea. I want to see lot of mning field entrance along side the walls. Also, do not put the river or waterfall right on top of the entrance. You need far enough distance or height between them. Can you post your design of the Sita's house revision? Thanks.
