I liked the seemingly chaotic format. It is quirky - very Brontosaurie. I liked the restlessness and drive of the second half. I think the second half reflects the first and does not seem disconnected at all. Iif you were able to expand upon the initial fragments and somehow make it into a fractal whole, it would be quite cool. Think Bach, Steve Reich.
If your goal was smooth transitions, easy listening, then maybe listen to some of the advice previously. However , if the goal is a story or a journey of sorts - a soundscape designed to invoke some vision, I think it works well - it just needs more work. There was nothing in it that I found disruptive to my ears, but then again I like a musical challenge - music to me does not have to be pretty or logical. I like things that invoke an atmosphere, and that atmosphere does not have to be like elk in the sunset, necessarily.
