Okay - this might sound harsh, but i'm surely not hating on your video:
- It looked like you tuned the saturation/blues up a LOT and i really didn't like the blue glare coming from the lights you had set up... it would have worked a lot better if you had neutralized the colors so that the light was white/tinted yellow.
- Biggest mistake: making the whole thing in slow motion, particularly on short rails like that, it just doesn't look that good.
- I didn't really like the text that you used I think that you should have compressed the different titles together more and put it in a corner by a rule of thirds? Hard to explain, it just didn't look very good
- A lot of the shots seemed to be from the side or diagonally, you should have done some from behind and/or in front of the rail
- I didn't like the cross-blur transition or the bright pulsing that you used, they looked pretty amateur and didn't really fit this edit in particular, though i do think they're applicable in some situations (in other edits)
- Otherwise, I think that the shots that you did have were decent, and you definitely went right when you were tuning the blacks and whites
