Resort

IMO columns and walls are way too sharp near the edges. Are the roof tiles modeled, or it's just a texture?

I use texture for roof. thanks for your comment.

In my opinion you should try working more with photoshop. The picture looks a little bit flat - try using the Z-depth maps to enhance the colors of the first plan and to add some fog effect to the third plan. Almost for every stone material seen from a short distance a displacement modifier is required. These are the first thoughts I came up with. Keep on with the good job.

thanks matciek85 for suggestion.
