Wow!!!! This is the coolest picture ever. I have never seen something like this. Crayons - the most useful tool for every artist. Can't draw without them. It also makes us remember our childhood. It looks like rainbow. Colorful like the title said. I love the effect which added by you too. That makes your picture looks more beautiful. There is a detail that I disagree: a green crayon is broken a bit on the top. I think you should fixed it before taking this picture to put on internert. That's all, once again I love it so much. Great work!
