So this is going to give you a rough idea of my process for each of these. Generally I do a very rough blue pencil drawing of the character or boss that I am doing. Generally I have up to 5 or six of these ready for the coming week in a stack. For this Solaire image the idea is to have a strong source of light in front of him and then perhaps a hint of the sunlight maggot in the shadow behind him.
I am really looking forward doing these NPC images since it gives me a chance to have a bit of back and forth with you guys in regards to who I will be working on next.
