I thought of that but they're quite 3 dimensional so a flat-paint representation of it would look like a cardboard cutout....just a little too 'fake'.
I'll add the 'shapes' to my paint and post a screenshot to see whether people would accept it as a compromise...
Edit....here's what I came up with....down and dirty 'quick fix'....will always look 'OK' in a screenshot that is 2D ...but in the flesh [in game] it'll always be a bit less than ideal.
I can upload this as a second variation....[when I do the right side too...and adjust a few details].
