Nice job
To be honest I thought the intro was nice. The sounds in the beginning were weird, but I liked them anyhow. Also, I think I heard the Stone Tower Temple theme after about 2:05. It mixed quite nicely with the rest of the song in my opinion.
For the rest there were some parts which I found a little less interesting. But that's probably not your fault, I guess it was the same in the original. Also I couldn't really imagine this to be a theme in a Pokemon game to be honest, but again that's probably due to the original and not because you remixed it too much or anything.
Overall 9 out of 10, 5 out of 5. Nice job.
