Aw... sad to hear that, why 3d no fun?
Love the atmosphere of these last few. The last one though... the guy on the left's values are fading away a bit too much I feel, the only thing saving him is the hot specular on his helmet. I'm not even sure those speculars should be there; while great for material identity, it's a cloudy-looking day.
Also re: artist's guide to guns tutorial... still organizing what I want to say and how to say it. I originally wrote up this big outline covering the entire developmental history of guns from invention to present-day and short notes on how exactly each one functions, and then I realized a) it's covered much better elsewhere, b) while it's nice to know for artists, it's not really necessary and far too much detail for a Draw Guns Gud 101.
But I am working on it.
