Nice walk through of Phil McDarby’s work on "The Green Man Awakens" here. He doesn’t go through actual steps, but you can see the progress from one frame to the next. It’s also nice to see the idea evolve along with the actual composition, since most walk-throughs seem to be 100% visualized in advance.
I don’t know about you, but I like to let ideas grow as I’m working, unless I’ve got specific instructions or some very particular goal in mind. Even then, I still like to let images ‘talk’ to me while they’re being developed.
The effect here is great, and shows how you can mix photographic composition with digital painting.
