While I'm working on a series of scientific illustrations I can't reveal yet, I thought I'd re-post this pencil (and the oils below) of a red knot in flight.

Originally created for biologist and conservationist Dan Rhoads' excellent and vital Migrations blog, you can read more about it at his site, and my two-part making-of, here and here.
Dan fights the good fight to save birds from the heinous hunting practices of migratory birds in his adopted home of Cyprus. You can sign the petition to stop the practice here.

Using some other photo references of Shelley and Steve, I polished off the portrait stage. As I've mentioned, using a projector sometimes felt like cheating. But after 20 minutes of using the projector for the rough above, I spent about 2 more hours without the projector finishing the portraits.
I like beginning with a portrait; it feels like a classic, solid foundation on which to start. Since blogs are so personal, it's an appropriate way to illustrate the blog in some instances.
Perhaps I should've realised here that the brains were a little lopsided and that this may not work. What I liked about it though, was the idea that our personas are masks, and we all wear a face in front of our brains.
I went for an unusual colour combination: orange, green and grey. It's not something the eye sees every day, so I hoped it worked. Here is the painting, as it was scanned before using Photoshop.
Sometimes, the artist just mucks up the paint, despite all the planning and careful drawing. I wasn't happy with the faces, and so using Photoshop, I tinted the original drawings, and overlayed the pencil faces over the painted ones. You can also see an early attempt at the text, with shadows hovering above the blurred Photoshop-extended banner. The brains are removed, giving it a cleaner feel. Scienceblog banners are pretty long and narrow, and the brains were perhaps not as pretty as they should have been.
At this point, I think the faces became a little too far-removed from being masks. Shelley and Steve were concerned. We began discussing something more mask like. It's good to know how far the client would like to push changes, so in the middle of the night, feeling all macabre listening to Juno Reactor and Delerium, I drew this:
Okay, too far. Shelley pitched the idea of going darker, and extending the floating banner to the right, and further into the colour spectrum. I hesitated a bit at the last suggestion: painting a spectrum on black is a sort-of shortcut to being eye-catching. I had to use my brightest paints, including real cadmium red. If you are going to go for it, you gotta go for it.
Much better! Using a bit of an emboss tool, I added a gradation-shadow to the faces. The background was digitally painted black, and a bit of the blur and smudge tools helped bring the red and orange paint together - even though in reality they exist on two separate sheets of canvas.
