Painting Miss Daisy

Using of one my friend's photos, I drew a pencil drawing of a cow.
I fancied having a bit of an experiment with this one, so feel free to tell me at any stage of the painting what you think of it :)
Here's the pencil drawing


and here's the first experimental background, using a mixture of cling film and sea salt.


Paintings under cling film take ages to dry - well they do on Arches 140lb rough, so this was all I got to do in the first day.
