Did some more work to Abstract 16 and this is what we have now. Here I have improved the foreground shape and I also decided to colour all the edges of the tiles in the background. This was mainly done so that once I start the large oil painting based upon this render it will be much easier to see which bit I'm actually painting. I did a big render with the older all grey background and it was going to be a nightmare trying to decipher it all. The coloured edges make each tile stand out better and also add a burst of colour to the whole scene.
