I feel we should just fix one common item to paint rather than just having open ended ideas. We will clearly see and compare both creativity and skill! E.g. paint a personal computer/paint a cell phone/paint Bon Jovi/paint a satellite/paint a music recording console (for @Forgiveness ) etc.
I have a similar cloud painting. Initially I thought it was done. After a few months I realised that it wasn't finished, there was nothing to look at. So, I built upon what I had and took it to a different level. This is fabulous and I think there is a huge potential in this to make it a great painting. Sign your name on it and see it after a month or two and then decide.
