Very recently I completed a small illustration for a finance magazine. The deadline was so tight that I decided to paint the background and foreground separately so I could speed up the painting process and adjust the final image in Photoshop much easier. The final result I shall post when it is published.
However for now I want to see what I can do with the process if I have more time, partly because it will be an extra option available to me during commissions but also because it should be fun. Another technique I have been dabbling with but not extrapolated is creating a grey acrylic underpainting and then glazing with subtle watercolour to give a desaturated feel.
Above you can see the final pencil work and a thumbnail next to it suggesting a possible background. Hopefully you can recognise Sir Chris Hoy the astounding Olympic cyclist. I plan to paint his portrait as realistic as possible and block in a very simple grey background with a white circle in the middle. I shall then draw out the Olympic medals on a separate piece, colour them in Photoshop and then create various backgrounds to sit in behind the portrait.
More to come.
