Would you believe it took two attempts to paint this picture and it's not one I particularly wanted to do! However I am pleased with this second attempt.
I normally use best quality watercolour paper which stays damp long enough for me to apply the washes and allows them to spread in evenly. My first attempt was on a very smooth surface paper, given to me by a friend, and it reacted very differently to the rough heavy weight paper I normally use. Another learning curve.... always use the best tools to produce the best results!
