If you like working with files, just wait until you get your hands on some good rasps.
Doing a round shape freehand is pretty challenging, as the human eye is pretty good at seeing where a shape is even slightly out of round. Your top profile is very close, but not quite there yet. I also would have tried to make the taper from the shank to the stem more gradual. As it is, the shank is significantly thicker than the stem, then the ring forms a cone, angling down to the thinner diameter of the stem. It would have been better to either make everything the same diameter or try to get it all to taper down more gradually.
