Nice Display of Pens and a Razor Michael,
Pen 1,(the Slim Line), the Bulb at the Nib end is very common, as it increases the holding diameter for easier control, but requires caution on the down hill, as it is easy to get too Deep at the edge, and create a gap, instead of a smooth transition.
Pen 2, The Transition at the Nib and Clip ends look fine, though the Center Band looks good on the Lower Blank, but appears too low on the Upper Blank.
Razor, The Transition at the Blade end, looks reasonable, though the angle of the Photograph, doesn't show enough. The Handle End, with the angle shows quite a Furry edge with something sticking up.
The Final Pen looks very good, only a small gap on the Center Band Transition.
I have tended to dwell on the Transitions, as these can Differentiate between a Good Pen, and an Excellent Pen, to the User and Buyer.
Your Items have many Excellent and Redeeming Features, Your Selection of Blanks, and your Finishes, are Excellent, the rest will come with your Continuing Recognition, and Practice.
Well done,
Brian.
