OK, this is a sketch I did on a plane ride from SFO to ATL earlier this year. It was a little over an hour. It is mostly a concept sketch to capture an idea.
Step 01 Line-work
Single layer to capture the shape and details.
Step 02 Color Fill 01
Airbrush color fill for the front detail.
Step 03 Color Fill 02
Airbrush color for the wings and a little back fill.
Step 04 HLS 01
Airbrush for some general volume.
Step 05 HLS 02
Airbrush for some addition details.
Step 06 HLS 03
Minor detail HLS.
Step 07 Shadow
Step 08 Ground
A little detail for the ground.
Step 09 Highlights
The highlight layer is what really pops the shapes with my technique.
Step 10 Notes
Notes for a little information.
Hope this helps anyone see a little more into my technique for fast concept sketches with a little detail. As with my other demo, this is 100% digital on a tablet PC. Now paper of guides.
