Adding colour and more "form"

I've been adding more geometry to the wall with bricks on corners and vertical faces to make surfaces look less flat and straight. This is most prominent on the window fitting and arches for the shops. I've also added two rows of coloured bricks which are meant to look scattered in a vague pattern. This adds some NEEDED colour to the scene. I feel with the red and blue bricks with the additional green ivy, the scene feels more vibrant, but not too vibrant that it strays away from the old, poorly constructed and depressive scene I'm after.
