Oh, no problem! I'm always happy to spend a few minutes blathering about my methods.
I used a bit of subtle color burn to pop the character against the skies in the first two panels, too. She didn't have enough contrast and it was easier to just push the sky away from her than to edit her.
Yeah, the caltropolis* is blurred. It's drawn on about five or six layers, each with an increasing amount of blur on them. Each layer also has an extra fill added in the appearance palette - the deep aqua, with increasing opacity percentages, which creates a sense of atmospheric perspective. All these layers are stuffed into another layer so I don't have to think about them when I'm working elsewhere, though that's more by habit than actual need, as that was the last thing I drew in this file.
Some people would probably do the atmospheric perspective by picking new colors, but I really love using global swatches. So I mix them by layering stuff in the appearance palette, or on the canvas. If I need to tweak the color mood of this page to fit in with the overall story it's just a matter of double-clicking the swatch, tweaking the sliders, and waiting a few seconds for the re-render (1200 paths with lots of transparency and a few layer effects takes a while for my little Powerbook to grind through).
When doing stuff with layer effects like this, it's usually best to apply the effects after most of it's drawn - otherwise it'll take forever, as it re-rasterizes every time you tweak a point. Tedious.
I also contemplated putting some complex patterns on the blanket with a distortion mesh (similar to what Disney did with the magic carpet in 'Aladdin'
but decided not to bother, as it'd just create extra noise.
