I really don't like the shorter scrolling text, it's moving too fast for my tired eyes. On the longer texts it was alright.
I don't mind the voice over man. Especially as it isn't just voiced over but a mix! I don't really like that you're talking over yourself though. It makes it a bit odd, so maybe mute that? I also think the voice over works really well with the picture(s). I also wonder what keeps you from adressing some of the stuff you voice over while you're riding instead. Like the track experience being more valuable for example
. All in all this is definetly what I ment with mixing it a bit. This is totally acceptable in my book. Nice video.
