Following on from Mr Hare (here) and Mr Cheetah (here), may I introduce Mr Kingfisher!
I've used the same technique - drawing first, then going over with a dip pen, followed by a very wet wash of acrylic ink. This time I did dilute the ink a bit first, but I'm not sure that was a particularly good idea as I've lost some of the vibrancy.
Anyway, once dry, I used coloured pencils and Neocolor II crayons for the detail.
Did you know, apparently, kingfishers dive so fast that they can penetrate a layer of ice to catch a fish!
