I posted an image earlier, of a mindmap which I created for the self-generated brief, which I chose to base around Location. A few tweaks, and here it is again.
You can see the development of shape and colour, in comparison to the first piece. Of course with specific colours, and the placement of elements, things can be brought forward and dimmed back. Ian enlightened me with these ideals, and hopefully from now, my work will progress in the same manner, but hopefully not lose it's 'subtlty' and become too over whelmed with shape.
