Not too bad.
I love how sharp that camera shoots.
gonna have to watch this when i get home (blocked at work, lamesauce)
pretty cool man
A little too much with the slider, I know it's a fad in the amateur car video world right now. But I would use it sparingly in the future. Oh and it looks like in the last shot your camera wasn't level, try using the internal level of the camera if your tripod doesn't have a level built into the head.
Nice video man, but like hipster said, use that slider sparingly. Another thing to note when using sliders is to try to avoid showing the start of side to side movement and cut the clip to after the motion has already started. Otherwise nice video, and put that 5DmkIII to work
