It´s beautiful. Can´t believe a 4 year old done that, mostly because of the harmony of the colors, the background follows some pattern, not just random colours. At that age he might not know why he is doing those things, but they come out from a talent inside, a certain sensitivity which will make him a great artist someday. And since it´s the first time I write to you, I ought to say that you are an incredible bass player, a brilliant musician and an inspiration to others, like me. Cheers!
