One of the advantages of having time to paint during the day is that I can take progress photos of the painting as I paint (if I remember, as most often I get totally lost in the painting process and forget about everything else).
After arranging the still-life, I lightly sketched the shells & seagull feather with Faber-Castell 9000 pencil (F hardness) on Fabriano Artistico CP watercolour paper. Since I knew that the angle of the sun will change while I paint, I painted the shadows first to remind me where the light was coming from.
Next I added the first layer of Winsor & Newton watercolour to each shell & piece of coral individually, working wet-into-wet to allow the colours to merge and mix.
After the first layer of the watercolour dried, I applied clean water to most of the feather. I kept some areas dry as I wanted them to remain white. I mixed Winsor & Newton French Ultramarine and Burnt Sienna together to get various shades of grey. I started painting from the outside edge of the feather letting the colour bleed down towards the feather’s rachis (shaft).
Next I started adding details, further defining shapes and texture.
I kept on slowly progressing around the painting.
At this stage I decided to finish working on this painting and added my signature with a pencil.
