These are all studies, the top one to show the technique I used to do the bottom ones. The video shows the whole process that took just over 2 hours in five minutes. The bottom ones are studies of the excellent BBC series War & Peace. I did them on my Cintiq Companion while freezing a frame on my TV. It was hard to get the colours right and I think that was probably, next to the composition, the biggest challenge. I really enjoy doing them but I prefer using reference but then overlay my own designs and ideas on top of it.
