OK I got educated, andpaid for two different sketches for two cover pages and flaps. This is only a preliminary research work on the composition. because that basic work was carried out on two pages of the cover + flaps. It's like 3 pages, which is a lot of work. He did: 1) a detailed drawing 2) color, he combined them. He Had to recreate it except Toto portrait and uses combined technique to keep the overall style (pencil + air brush). Since it is fairly complex and unique, it's a fair price and seems to be the usual amount of our agreement.taking into account additional future work on the texts and this sepia version.
