I think your stuff looks really nice on the surface. Lots of attention to detail and compositional consideration. On the spectrum of style and substance, you're a little heavy on the style side in the execution of projects, but that's a perception likely amplified by the general emphasis on visual experiments and personal projects in this montage. I'd imagine that once you have free reign to show paid projects, that'll probably shift a bit.
Two things to consider might be:
1) Use the camera more. It can be a really useful element in most shots, in terms of communicating to the viewer. I say that not because you don't know it, but because most of what you're showing follows from a line of thinking akin to "here are the elements of my composition, and here's how they're gonna behave and move through the frame." So you're basically deciding to lock off your shots and rely on elements to do interesting things in a fixed frame. And that's fine, as a choice, but it occurs to me that you're making that choice a lot, and not necessarily to your benefit. And I'm not suggesting that you start flying the camera all over the place on every shot, but there's a lot you can do with it, if only to activate the frame and give the viewer just a subtle sense of place, or focus, or activity.
The camera, albeit itself unseen, is a major actor in your shot. Feel free to use it as such.
2) In the montage itself, consider how your editing interacts with the audio. Don't be precious with the length of your existing clips. Break up the pacing and allow your cuts to play with and accentuate the audio. It will energize the entire piece.
