An absolutely beautiful hummingbird illustration by paperfashion, AKA Kathryn Elyse:
According to the etsy listing, it's pencil, ink and watercolor. That tickles me, because yes you can get those bold colors in watercolors, but few people do, and I thought it might be digital. As you can see from her etsy shop (where you can buy a print), the artist predominantly does fashion illustration -- but then, this hummingbird looks like it's wearing bird haute couture. It positively glows.
Painting by Kathryn Elyse, based on an original photo by Jose Yee. (The photo is on a velvety black field, so it's very different, but they're both incredibly strong images.)
