I'm asked lots about what paints I use and how I paint. Here's some photos of the beginnings of the process for you. I try lots of different things - this time it's underpainting with green - and I like to experiment so it's not always the same for each painting.
Getting everything ready and choosing the paint colours. I have a separate drawer for yellow, reds, greens etc - it helps no end.
Below, adding the flesh tones all over, and right, adding some highlights to show the lighter areas, and yellow ochre for the darker. Tip: always go over the lines as you don't want harsh edges and that includes the hairline.
It's now a question of building onto it all. I may decide to leave painting the figure at this stage and move onto the surroundings just so that I can maintain a colour and tone balance throughout the whole.
