Airplanes!

Here's a couple of test pieces I did for a french publisher last year (colors by Giusy Gallizia).

I was absolutely sure i drew Spitfires, but some people online pointed out that it
looks more like a Hawker Hurricane, and people online are always right.
To this day, I still can't see the difference between the two anyway.

I also drew this Albatros D.V.
