I am currently working on a couple of identification boards to go in a bird hide, one for summer birds and one for winter birds.
I will be doing a large background illustration of the lake and surround together with all the birds to be seen there. I have started on the winter birds and here are the first three, 18 more to go for this board.
I am using watercolours, mainly for speed. They are not large, measuring about 5" at the widest, but will be reduced down a little once I drop them into the main illustration. Good ole Photoshop, makes the job much easier.
