While they sound very nice, they are simply too long!
The first track has the same chords repeated over and over again which would be fine if the fat was trimmed a little. Combine some sections and even though it might hurt, cutting some sections would also help.
It really wouldn't be as big a deal but its the fact the percussion and chords are just recycled for basically 11 minutes straight. if there were more varied percussion or chord progressions, it wouldn't feel as repetitive as it is.
The same sentiment applies to the second track but to a lesser degree as I feel it has more unique sections and I also just prefer the instruments used in that one more. Though the part with the constant riser is a little too much that it's distracting.
