Whilst browsing I came across the Diva Challenge and thought: "Why not?" The simple challenge "The Undulating Tangles in C and S minor" was exactly what I needed.
Only after I finished shading with pencil did I feel that a bit of colour would add interest. Bad idea! The yellow and orange Polychromos look dirty. Next time I will erase the shadow first and then colour.
Important is, my office reflects 'creative untidyness' - so much better to work in ;-) The challenge was fun I will make a point to check every Monday to see what new challenge awaits me.
