Bob Davies (art tutor)
Here is a link to a brilliant art tutor who offers a free e-book and free video clips which can help you a lot in your progress. He offers advice on how to get started with acrylics, watercolours, and oils. There is of course the chance to buy his complete set of DVDs.
The painting above is one of my own acrylics. So have a look and see what you can learn from Bob.
