Very cool painting! The angle is dizzying, and you seem to understand the way the craft are constructed very well. It seems to me that the lighting on the closer plane is a bit inconsistent, though. Is the light source behind the viewer, or more to the right?
Also, the farther craft isn't as convincingly rendered as the near one.
Thanks ! Everything you say is very true, I very often start with an idea and finish with something else ! The craft in the background is actually one of a friend of mine, I drew it quickly to make him smile ! Thank you very much for the nice comments ! I ll pay extra attention to lightsource next time
