OK guys,
There is only
one aircraft here, and no deers! (unless there's something you can see which I did not draw....)
"but then I tipped my laptop and noticed the big dot in the middle went red"
Wot you on
Mechta?
If you turn the picture upside down, it simply re-orientates the aeroplane,
which is what usually happens in my experience.
Scratch built pic, so do take your time!
