It's also very much like a diagram I once saw demonstrating the optical illusion that two parallel lines are convergent (divergent if you like) when it is just due to the oblique lines in between. Sorry, I searched but could not find the same diagram just now and the one I saw was in a fifty year old school book I used to own.
You should know that we have more faith in you than that!
I like the warmth that your additional tinting has teased from the grain of the wings.
