Joesph Zbukvic and Alvaro Castagnet are my two favourite watercolour artists and the DVDs are excellent. Watching the DVDs is a constant source of inspiration and the ability to go back through these lessons time and again in minute detail makes them worth every cent.
I particularly liked this rural DVD as a lot of Joseph and Alvaros works are city scapes and this DVD helps in understanding what is required to paint country scenes
