Historical review
A review by me... for me! Over the last 2 years, I've learned to make GREAT thumbnails and videos. I don't relent until its JUST right. The maximum amount of time i've spent editing a video is 100 hours. It was this one right here, with over 20 hours of footage which I condensed down to 30 min - https://www.youtube.com/watch?v=d63uEJahsFc. If you like what you see and read, contact me!
