Hehe, cool stuff.
I don't do much on paper, just occasional concept art like that taxi, which are scanned and coloured, concept art for someone else to 3d model from.
I don't do much other than occasional graphics for this website outside work, I just cant be bothered after doing it all day but I could do with getting back into it - since it pays to improve my skills- playing with toys doesn't get me anywhere lol
I use photoshop with an A4 wacom on dual monitors, and maya at work.
