It's looking better, more in keeping to the surounds, and taking on board and trying peoples suggestions is proof yo want to make this as best as it can be... For the window you could try some of the Port windows or the window of the inside of the ship, the round windows, giving it a more nortical beach like feel.
On the tile set you could give an option of say having the wooden boards meeting the ground, IE place some rocks around the bottom of the wood to make it look like the wood is embeded into the ground...
On your tile set, you could leave the white version previously did and add various windows... I very rarely discard some thing I have made as other people have different opinions, just give more choices, that's my best suggestion.
I would say tile set making is the hardest to pull off, so in my opinion your doing well.
