Another brick in the brick wall

My aim was to do a huge monochrome structure and then have some colours wildly pop out.

 

My first try also had different pink trees within the city but it was too much. In fact it's still too much and could be cleaner, but I like the overall impression.

 

I think the samller picture without the tree works better... But this picture was done for the "great wall" contest. So I had to deliever something huge, I guess?
