Overall, nice look. Looks flat and washed out, kind of a vintage look. Next time, I would try to reduce those sun flares on 00:16:00 sec. If your matte box isn't enough, try to extend it with french flags or just simply put your hand on the spot where the flare is coming in. About the noise, it doesn't really bother me in this video. You will always have that gorilla grain with the BMPCC because of the small sensor.
Why buy the DJI Ronin? Ever since you are a student, I recommend you to buy a Glidecam instead. If you practice enough you will get smooth shots as well. You can always rent a Ronin or buy it later if you have more work. You can spend the money that you save on the Ronin, on other parts. (f.e Metabones, microphone, lenses, etc.)
It's obvious that the GH4 records in 8-bit 4:2:0. Look at the gradient at the back on the wall. The one of the Epic is much smoother. I would like to see a comparison with the Epic and GH4 with Shogun attached.
