Before to airbrush clear varnish, I had to do some things I've forgotten...
First, I completely forgot to place the decals on the propeller!!! Not a big mistake of course, but I'm glad to have seen that before to continue the work...
Then, with a razor blade, I've cut the decals of the eyes and the mouth to follow the lines of the cowler...
Razor blade...

Rapid check: five to left hand, five to right hand... Okay, my fingers are all present!
