Did this drawing on sketch paper (top) back in my teen years, then decided to clean up and enhance on Photoshop as shown on the bottom image. I really got into Air Force illustration since my dad used to work for Northrop Grumman back in the late 70's to I think the mid 90's. My dad is an amaizing artist. Jaw dropping art. When and if I get a hold of some of his work I will post it.
