You've definitely got a style going on here, and that's a good thing, make no mistake. These pictures look like they were made very deliberately, and they use some "pro photographer" tropes like shallow DoF and so on, so it's instantly clear to everyone that these are pictures that were made like this, on purpose, by someone in command of the technical side of things. That's a big part of what "style" is about.
Unfortunately, this conceals something. Because we look and we see a bunch of technical stuff, a bunch of style choices, a bunch of signs that these are Carefully And Well Made we miss that the subject is simply banged in the middle of the frame every time. You're not spending much effort at all on the part of the process where you choose what goes into the frame and, more importantly, where it goes in the frame and what else goes into the frame with it.
Is this a bad thing? Eh. I dunno. You have a heck of a good subject so it's certainly not the end of the world. A good subject banged in the middle of the frame is a fine picture much of the time.
I do think you could make stronger pictures with better framing choices, and a better "whole image" approach. You'd be hampered by the extreme shallow DoF you favor, since everything else in the frame is likely to turn up as fuzzy blobs of color. On the other hand, some fuzzy blobs of color, light, and darkness -- well placed -- would not be amiss themselves.
Just to be clear, you've got a lot of good stuff going on here. I just happen to think there's some specific things you could do to push your pictures up a notch.
