Here are some flying vehicle thumbnails I have been able to squeeze in over the last couple of weeks. The technique is difficult, straight black ink calligraphy pen on white paper. As a result the perspectives are a bit loose and the designs unrefined. The goal was to try and explore many different asthetic forms with the focus being the graphic shapes seen within each design, hence the use of the unforgiving medium. Eventually some of these might make it into "Concept Design 2". I'll probably pick a few to refine and then pop them into some of my environment studies. Also I plan to use a few of these guys for my "How to Draw Vehicles" book which is coming along slowly. Each sketch took about 5 to 10 minutes.
Anyway, back to work, hope you enjoy.
