Two observations. Although I don't have the Osprey, I have found that soft-sided bags really benefit from a folder/cube system, giving the bag structure it otherwise lacks and organization that makes it easy to find what you're looking for.

In addition, it is extremely easy to overpack a soft-sided bag, and by extension, exceed whatever its rated dimensions are. I've noticed that a very overstuffed bag, even with compression straps, may exceed its advertised total linear dimensions by five or six inches. I think this "feature" partially explains why so many overhead bins are stuffed with bags that officially are within carryon limits. Your packing list seems pretty well organized and undoubtedly kept you from overpacking.
