Paintings number 1 and 4 are by Nathan Fowkes. He is an artist that I truly admire. His knowledge and application of colour and light is something i strive to gain a greater understanding of. His original paintings were painted in Gouache and watercolours and can be found on his sketchbook blog http://nathanfowkes-sketch.blogspot.co.uk/
Paintings 3 and 5 are by Edgar Payne, another artist I highly respect. The colour palettes he used are really interesting to analyse.
Painting 6 is by the awesome Craig Mullins. A digital painting master by all means!
