I usually (as most designers and photographers I guess) create several versions and sketches for each work. As a consequence there are always a lot of pieces in the drawing board, and I usually tend to employ it in other projects or simply for personal explorations.
The mockups are from: Mike Delsing, Designalot, AlexandreCardoso and AnthonyBoyd.
Comments and criticism is more than welcomed.
