Just GREAT!
I must say this is exactly my taste! Such a cool arrangement of happy instruments and patterns.
There's nothing i don't like about it! It's just great for me and obviously for many others.
You have a great feeling for melodies and a true talent. As you have shown here it is sometimes unnecessary to spend to much time with details and very effective to make use of a spontaneous creative flow to deliver excellent results.
I'm impressed.
