That is better than Bob Ross. I don't mean to step on any ones toes but when you said drawing and painting class I pictured a Bob Ross style - cookie-cutter- pretty landscape. What is the point of painting if you are just copying someone else's work?
But yours is original, to me that is what "art" is.
PS - I love Bob Ross, someone on another board I read signs their posts, WWBRD - what would Bob Ross do? Paint a happy little tree.
God Bless.
