Between 0:32:00 - 0:34:00, there's a high tone instrument playing a high note and one few notes lower, however, these sound false. I believe the second note to be lower originally. I think it should be about 1 or 2 notes lower. Note that I'm not a music expert in terms of creation, I merely enjoy works of others, so my terminology isn't the best.
However, I did most certainly enjoy this remix. Taking a different approach than others is always a good idea, and you turned that idea in a good result. I believe, in addition to the above, it does require some finetuning. I'm not sure whether you used the original or recreated parts of Speed Highway, they sound like the original - if you did recreate them, you did an extraordinary job at it. I do suggest to rethink certain parts where both songs are mixed, especially those where the beats don't always match up. Some parts don't feel right like that. Perhaps some Speed Highway could be recreated in the style of the Chemical Plant riff, mixed in in a different way than the 'overlay' style used now. That's just an idea, though, I'm not sure how to work that one out. As for the rest of the song, I did miss Speed Highway single parts, whereas you did gave Chemical Plant some alone time. EDIT: Ah, at the end there was some Speed Highway alone, without Chemical Plant. Ignore what I said, I just missed that >.<.
Perhaps my words are of use to you, I really hope this critic can contribute to the song. It was a pleasure listening to this (and will continue to be, totally kept that mp3. x3)
