The Alchemist by Paulo Coelho. not my favorite but one of the first english fiction book I finished reading years back. Cover looks like simple shapes but it's a small hint of what happened in the story(not the main twist though). The squares are the pyramids of egypt viewed from above. the swirl shape? you gotta read the book.
Here are my thumbnails. (The first image is my submission, the others are just my practice versions. I included them because I don’t have source photos.) I learned a TON by doing this. I got a much better handle on water control, and composition simplification by painting these thumbnails over and over until I was happy with the direction. I intended to paint landscapes reminiscent of scenes you might find in my home state of Ohio. In each scene I tried to incorporate a mix of lost and found edges to help evoke feelings of nostalgia and solitude. These are all watercolor on paper. (Daniel Smith pigments, and 140# cold press Arches paper.) These were painted with Escoda Reserva brushes sizes 4 and up. For each thumbnail, I used the same palette consisting of Carbazole Violet, Cerulean, Phthalo Blue, Cobalt Teal, Ultramarine Turquoise, Pyrrol Orange, Prussian Blue, Indanthrone Blue, Quinacridone Rose, Carmine, Raw Umber, Burnt Sienna, Hansa Yellow Light, and Quinopthalone Yellow.
Here's my entry for this challenge. A demon monster of some high status fighting another high status monster. What are they fighting for?
