Jean's blog about them and it was the first image we did in the loose group...... they are not as difficult as they may seem if you follow Jean's instruction and I have been working on them ever since.
This is quite large 20"x25" as I am still on the trail to paint bigger and this is smaller than full imp (22"x30") though larger than half. Have used Alizarin crimson, pthalo turquoise, cadmuim yellow (I don't use this much but am liking it on here).
I did this without reference and it started out just as a play to see if I could fill the paper!!! Am still working on the painting I was doing at the same time.... that doesn't seem to be co-operating like this one did.... it's a flamingo and am having difficulty seeing how to finish it... watch his space!!!
