I don't know how much is you, and how much is the lens, but the simultaneous presence of depth of field on the subject and shallow overall depth of field in these shots is spectacular.
Any details on focal length and shooting aperture?
About 90mm and f4, all shot at f4. Admittedly I shoot fast lenses fully open since years now and have developed a (my) style, to guide the viewers eye using sharp-unsharp and position of objects ;-)
Interesting look, seems to work well for pictorial photography. Is it a short tele perhaps?
As mentioned above, it is about 90mm focal length, so yes, well noticed, a short tele although for a printer (= enlarger) lens, that term is uncommon and not used. It is only about the magnification and image angle.
