I was able to get a bit more progress on Smaug last night. I added some lighter tones to the wings and re-shaded some of the scales. For the scales I'm airbrushing them black and then will edge highlight them by hand.
Any thoughts on the colour for the wings? Does it need to be more tan colour (less orange), or is this looking ok? Its really hard to get good source images because anything from the movie has very harsh lighting.
