Summer on the serpentine

I really liked this class, I'm a relative newbie to painting so this helped me build on my new awareness of analogue colours and contrasting ones. I had made a few errors but perservered to fix them, circling back to a reasonable composition ...(V shaped?) I found doing lines a little challenging, would love a class on how to do lines and brushstrokes? It seems like something U learn in art school but not as easy to access methods to get, say, super clean lines..and brushstrokes seem to be harder tha u think, to get 'in and out' without making a mess and keeping coloyr fresh! But George's classes are perfect for the beginner and even intermediate. U are totally free to build on his ideas. (I added dots but...not sure about that idea lol!) Thanks George, any advice welcome!
