What colorset did you use?
If it's default, I would maybe add a bit of the pastel orange and the lighter pastel yellow. That way the stones will look way more desert-like.
I know these are more brown and took place when my map, Rusty Desert, was still around. Look at how the bricks seem to match the landscape a bit. Imagine ancient Egypt. They used mud and sand from the area around them. The gray bricks do not match.
(Ignore the metal doors or anything out of context from the normal brickwork, but look at the theme and how it matches the landscape)
