As mentioned in my perious post, I've hired to draw a book cover. The author, Aaron Pogue loved the chacter sketches so I did a series of thumbnails. Of the half dozen I drew I liked these three and sent them to Aaron.
I had met face to face with Aaron and he gave me the big picture of his book and the entire series. This cover was described by him as a girl thief, in a balcony garden.
(Incidentially, I asked f it was okay for me to use the art in my portfolio, blog, etc. and Aaron kindly gave me premission. You should always ask, not every client feels the same way.)
I haven't heard back what Aaron thinks, but I'll continue to post my steps in this process.
