these rough sketches are a good way of finding out if I am planning the right colours! My first choice of a glowing yellow florist just did not suit the painting...so I ripped up some rough paper, painted it with blues and stuck it on...much better and will of course show off the flowers so much better. I also will change the red on the left to something maybe more bluey.
Here is a detail from my painting of the Old Shades which has been accepted for the RI in March! woooo!
