Colourful art master piece

Lately for writing we have been working on this masterpiece. I spent a long time on this. What I disliked was how long it took me to finish. What I enjoyed was the finished project. Next time I will try to make it look a bit nicer. This art represents our hand as the tree reaching out to say "We need to save the earth."our hand is the trunk. The colour bursts are made from the primary pastel colours.The colour burst represent oxygen in the air.
