It was really great bro! also sorry about your friend that's sad man, but this was a great memorial song you did, about the Camera, I would say that's awesome man, but after that you need a stabilizer which makes your videos smooth, with some cool tools you can make amazing videos, though your older videos were already awesome! but as I can see you are improving your tools so I wanted to say that then you can use some of those tools to keep it and also a video editor which you can edit colors and lights and even zooming in and out or moving camera from a side of scene to other side, or even stabilizing inside the software. :D the ones that I know are Adobe Premier and Vegas Pro which I am using Vegas Pro.
