I also love the music, and I think the text has potential with some tweaks. I will second @Fastbee's comments about needing more attention to the modeling, textures and lighting. Your camera moves are also quite rough. Try to be more subtle with moving the camera and think about what kind of story you are trying to tell. Is the camera move helping tell that story, or is it detracting? It really helps to use camera rigs in C4D. Even something as simple as a null placed at the center of your object and your camera as a child so you can just rotate the null and the camera moves around in a circle. There's also the "target" in the camera settings, which you can drop a null in there and control where the camera is looking. The Camera Morph is also a great way to get simple, easy-to-edit moves.
As for the idea of this drone, I also don't see how this would be a good idea. First of all, these types of GoPro rigs are pretty outdated at this point. Plus, you definitely don't need two of them. The company I work for does 360 footage with drones, and even back when we did use a similar GoPro rig, we just put one GoPro on top of the drone looking straight up. That way in stitching we could patch over the drone with the footage of the sky above it. It looks like you have a gimbal on the bottom rig which will stabilize those cameras, but not the top cameras. If any camera in a 360 rig moves even a millimeter differently than the other cameras, this will throw off your stitch. Your top camera(s) would become completely unusable. Finally, if I were in the market for a drone, I would not buy a 360-specific one. The camera tech is moving so fast that, unless it is modular, it would be completely obsolete within 2 years.
Sorry if you feel like we're ripping you a new one, but you said you wanted honest CC! Keep trying- you will get there!
