Michi: I don't think copplestone streets and medieval houses are contradicting. But the second thing that I am unhappy with (apart from the foamboard carvings) is the painting. I am not happy with the colours at all and I will need to experiment a lot more until I find colours that make it look better (anyone?

)
Actually no, as I find no fault with the color. It reminds me of wet copplestones. For dry copplestones the colors should be lighter, maybe brush a tiny amount of sand color over them afterwards. But apart from that they look just great.
