I very much appreciate everyone's comments on my painting of this classic jet. It is very much appreciated, even any negative comments, in fact, maybe more so.
As far as sky colors go, there is certainly some artistic license in effect here, but you might be surprised how colorful clouds can get, even with blue sky above, if the sun is low but still casting light far above. I've spent decades looking at skies very carefully. Of course, these effects may last only a minute or two, and as an artist I have no problem saturating color for effect. As far as the sun glint on the canopy, with this series of what I call "artistic profiles," I've included it on all of them, including all the World War Two planes I've done.
Thank you all!
