The final image, some texture and colour added on top. I try to add tertiery textures now at the end to avoid me going in to too much detail in the rough sketch. This allows more importance on the base form/silouhette of the image.

Rough sketch done in Sketchbook pro. I tend to use that for quick doodles as to me it has a slightly more organic feel (for doodling/sketch work)

From the base sketch I take it in to photoshop to work on tones and lighting. I still want to maintain parts of the sketch look within the image if I can.
