For a first ferrule change it's not to bad. Looks like you had some issues with facing. Maybe your having runout issues?
Also make sure your ferrule is nice and flat. It also looks like you have sanded the ferrule a bit much. Make sure your shaft is spinning nice and true, so you can turn down the ferrule as close to the shaft diameter you can. If you want to use Ivorine, LBM or other ferrules with big pores, seal the ferrule with CA before sanding. When trimming the tip make sure you don't trim it so it gets a taper, like the one in the picture. I prefer to use a freshly sharpened HSS parting tool and trim it as close to flush with the ferrule as possible. Another tip is to get a set of quality magnifying glasses. I use a Optivisor #5 what a difference it makes for precision jobs. Use a longer setting epoxy, BSI medium cure gives better results than the 5minutes one. I prefer to use the West G/flex.
