Painting a scene with airbrush

This was an interesting experiment! Should I try more of this kind of thing? Though I've used the airbrush for painting wood carvings for years, I've never tried it for a two-dimensional scene. This is quite small, just 3.5 by 4 inches.

It started out slightly bigger, 4 x 6, but I spilled a blot of red ink off to the right and ended up cutting off that section. Also added an accidental black blot half way up the big dark tree, so tried to incorporate that in my painting.

If I do more of this I certainly will have to be more careful to not get unintended drips on it!
