Thanks for the compliment.
Essentially the image with the focus on the airship was what I had posted a couple pages back except that I had added the sepia tint to it. The other image was focused on the woman. I was illustrating a point about what the artist wants the viewer to focus on. Between the two renderings, I would submit the image where the airship is in focus and the woman is not. The expression on the face is important, so I didn't have her out of focus to the point where her face was a complete blur, but as much as I wanted the expression, the airship is still the primary element I want the viewers eyes drawn to.
Oh...in that case, I don't care for the sepia version on page 17 as much, because I really like your color palette! The two versions on page 22 seem slightly different, color-wise, and while I like both I prefer the slightly brighter version--I think. I agree with you that it works best with the focus on the dirigible, although I could go either way on this point, too.
If the woman is out of focus, I think the brighter colors help to make her stand out relative to the rest of the scene.
