This was my entry for the Bronycon 2017 PMV Contest. It didn't place, but have you seen those videos?
I still feel this is one of my more visually impressive efforts, especially since I didn't use After Effects.
I really tried to see how Sony Vegas works with 3D and it produced some good results.
If any pro editors see this video, I'd like your feedback on improving from here.
