Allen Douglas is a freelance illustrator working in the genres of fantasy, science fiction and fantastic art.
His clients include Penguin Putnam, Tor Books, Berkeley, Random House, HarperCollins, and others. His work has been recognized in competitions and publications including The Society of Illustrators of New York, Step By Step Graphics and the Spectrum collections of contemporary fantastic art. It was in the most recent edition of the latter, Spectrum 17, that I noticed his work.
Douglas has interestingly different, sometimes quirky, takes on his subjects, combined with moody, atmospheric staging of his compositions and an often subtle color palette.
His website features a selection of his work. Be aware of the small arrow at the top of the page of thumbnails to a second page. When viewing the full size images, the click-through progression stops at the end of the images included on the first page.
There is also a gallery of his work on the Tor.com site.
