Marc, that is one sweet, sweet Stearman. I have two in the stash and your build is a real inspiration.
A couple of things that stood out to me - your engine and prop (nice little detail using the aluminum tube on the prop hub!), and that amazing choice of paint job. The gray and yellow Navy birds aren't all that common, but damn if it isn't a cool color scheme.
I masked and sprayed markings for the first time on my most recent build, and I'm hooked on it, too. I don't suppose those masks you used are available for purchase anywhere?
Again, you've done really, really nice work on this.
