Youtube botanical art videos
Australian botanical artist Helen Fitzgerald has been kind enough to create some wonderful videos where she demonstrates her botanical painting techniques.
As well as regular videos, there are also videos made up from still shots with a voice-over describing what is going on. I found these were particularly effective as you are able to study what is happening in each shot. Here are some examples.
