What are you most proud of? How the colors went together and that it really works. And using zippers from the 1980s that I had after cleaning out my Mom's amazing sewing stash. And the detailed quilting I did outlining the leaves and berries in the pattern. What advice would you give someone starting this project? Look at as many photos of finished duffles as possible. If you're going to put this bag to a lot of use I think a sturdy zipper for the main zipper is a good idea.
