I considered cropping the top of V1 so that the red bricks emanated from the top left corner, but it removed too much of the blue tiles, so I went for balance instead. The same applies to V2. A necessary compromise. That's my excuse, and I'm sticking to it!
5 versions, 4 of the wall detail, and the 5th one showing the wall and stairs in context.
Please don't judge the 5th image, it really isn't very good, but is the only one I have to show you the whole wall.
