All right this has great potential you have marvelous ideas, the arrangement is very nice. On first track Memories of Blue, don,t be afraid to use sustained pedal on the piano, you can probably change your voicing on the strings to make them sound wider even if the plugins is not the best of the best it will enhance A LOT your tracks just like that. Your lush choirs is nice but I think you can play with a bit of reverb and look with volume automation with fade in / fade out to create a better transition between those. Other than that the composition is really good. Well done !
