Just a simple illustration I put together experimenting with adding watercolour to a fineliner painting. The ink in the fineliner and the watercolour pigment react creating an interesting cloud seen in the top right hand corner.
Despite the different hues of blue, I stuck to Phthalo blue only. But water and the fineliner soon created lots of interesting blues for me. Once the piece was dry I added and outlined my peacock with Indian ink and white pigment, this painting is also available in my shop!
