Of course, I do. Sometimes I'm not completely satisfied with how I've written a scene, but I also think I'm quite aware of my limitations as an amateur writer, so I don't stress too much about seeking "perfection". I usually take the first draft as good and the changes are really minimal. One fic I wish I'd written differently, however, is "strawberries and cinnamon." I reread it a few months ago and noticed all its flaws for the first time. If I rewrote it now, it would be quite different.
