This one also just worked. I love it when painting just work. These birds are found around the arid and semi arid interior of Australia. They measure around 11 cm in length and weight between 9.6 - 13 grams.
Painted Firetail measures 2.5 x 3.5 inches and is painted on 300gsm smooth Arches watercolour paper.
Many thanks to Jim Bendon for the reference photo.
