Thank you so much for the very nice comment, it means a lot !
The progressive bands that I'm into (such as Rush, Fates Warning or Opeth for example) tend to have those calm intros before building up progressively their structure, which is something that I really love in their epic songs (and tried to bring in my composition to have more variety, and create more contrast so that the heavy part has a bit more impact). I also really like how those bands bring subtle complexity in their songs with time signatures changes and non usual arrangements, which is also something that I tried to emulate in my track (with each main section having a different time signature and the changes in the arrangements in the second half) to bring in more depth.
Anyway, thanks a lot for the comment (and as for the top 10, only time will tell) !
