EDIT: Wrote this before PC replied.
I just listened to the video and I guess nobody has replied yet, so here it goes, with the giant caveat that this is just my personal opinion:
Thing is, it's by no means terrible. Everything is executed well, well mixed etc. But my issue is that it's "prog by numbers". Keys? Check. Meter and key changes? Check. Instrumental section? Check.
So, all the pieces are there, but in all those sample in the video I didn't hear a song.
To make it more constructive, let me ask you, how do you guys write songs? One danger with these big prog bands of 5+ members is that they attempt to write a song together. What you get in the end is a pasted-together sequences of ideas. Problem is that prog almost invites this kind of writing because non-sequitur transitions are almost expected.
