Re., Natebros' comment: I think your illustration does a great job of depicting the ambiguity of von Richthofen's death--he is stalking Lt. May while Lt. Brown gets in position to shoot at him from behind, while he is at the same time flying low enough to be in range of gunfire from the troops on the ground. Canadians like to believe that Roy Brown shot down the Red Baron, since Brown was Canadian. Australians like to believe that it was ground fire that got him, since the AA fire came from an Australian battery. The Germans sided with the Australians, as they didn't like to think that their top ace could have been bested by another fighter pilot. From what I've read, though, von Richthofen had been suffering from a head wound or head trauma, and this quite likely would have impaired his combat judgement considerably, leaving him vulnerable to either danger. At any rate, I love your illustration.
There is no definite answer, but it is believed it was ground fire that killed him. He was fired on by Brown while also being shot at by Australian troops. I've tried to show the moments before he was shot. I added the troops and Brown's plane to give the option of either scenario, which ever is right.
I didn't feel you were trying to rip into my art, sorry if I am coming across mean, I was just trying to explain my thoughts and how I came up with the concept through the research. Thanks for the comments.
