Hiya namelessshadow.  From what I see only two major changes.  First is on the tan/white pillars, you want to break up the square/rectangles with some shading or highlight colors.

The second thing I see is an interaction on the right side with the tree and the background.  The white on the tree kind of gives the illusion of background and no foreground so its creating an odd transition that should just be a break.  Maybe add somehighlight color as a border on the white and the background?  Im not sure of that though.
