You did a great job, I'd be happy with how both tanks look now. Unless you want to restore both bikes to concourse level, don't let the odd imperfection bother you, riding them is what it's all about.
Don’t crank on it so hard. The heavy gauge steel won’t move as easily as the 22 gauge the PDR guys work on. The light hammering around the edges of the dent is to relieve the pressure on the steel built up from the dent. For old tanks you have to sand and fill anyway. Also put something between the rod and the filler neck.
