I didn't attempt to post the newest sprites or mock-ups. As Glide said the sprite has changed and the shadow of the palm tree has changed. As I stated, the other artists appreciate the critiques on all the mock-ups made by them, and I do also, but that is not what this topic is dedicated too. I updated the first post to make it easier to comprehend what I am asking for. It is most likely my fault for not making it clear enough in the first place.
I am looking for critiques on the furniture, floor, and wall tiles because I feel that the style isn't cohesive with the current tiles in the mock-ups made by the other two artists. Also, I feel that some proportions are off and any other help or ideas on how to make the furniture, floor, and wall tiles better is welcome.
Edit:
I put an hour or so into trying out some cave tiles, here is what I came up with.
I thought I should post them here for critiques before I go any further. Obviously they are very mucky so far, but other then that I feel that they look more like a mountain cliff then a cave platform.
