I really like this. It's nice and simple with kinda of a sad, memoryish vibe that would be great for a cartoon with a serious message. Added to MP3 player.
The two beginning themes do sound A LOT like Vangelis' "Hymne" and "Anthem"
About the rest, it flows nice and it's good to listen just to relax.
Please contact me if you would like to use this in a project. We can discuss the details.
