I'm enamored by the work of Portland Maine artist, Josh Brill. He creates modern illustrations of birds and animals in an ongoing series he calls the Flora Fauna Collection which captures,
"The design identities of plants and animals from around the world. Examining the visual character differences and similarities of species. A field guide of discovery, beginning with birds."
Josh's website Lumadessa features a number of prints for sale ($10-$30) along with free smartphone wallpaper (my phone is currently sporting the colourful Western Tanager (above middle)).
