Well, I could say my opinion for the track selection - it is rather unsatisfactory - to me. About the flow - here should be good as far as I could assess this. And technically, transitions and special techniques, I can`t judge this.
And about that the whole is not nice .. well I think this cannot be explained further .. lets say it in this way, imo if there are some/several pretty remarkable tracks in one set, then it is fine, but strictly said, still not completely good. All of them cannot be remarkable. Thus is as well your set not overall good. But it seems that I do not find even 1,2 cool tracks(, still).
