The one on the right was fun and interesting, the character is way more serious and somber for such a pose. And the one in the middle was a bit more serious, but we wanted the character to be still, and imposing. So the one on the left was decided upon as the best option.
Now, after some reference images, the final sketch is complete and ready for line work. The face was modified to look like the client, but I won’t show his photos (gotta respect the man’s privacy, y’know?).
