Hmmm- Let's see: Aussie Beer vs. Virginia Ham--a good bet, huh?!
I love this site and the various ways people interpret lighting (infinite solutions). My classic lighting is sun high above the aircraft at 10 o'clock in side view, offset slightly toward viewer in plan view. I think profile renderings of Mustangs will be close to Jade's shapes in that bottom wing root area. Tullis has it right on this one.
Like Grubby says, great work, Jade! Any more subjects in the que?
