All of this sounds cool :) One thing I would try is doubling your more natural sounding piano with something more synthy so that it can have a better time blending with the synthy strings that come it(for longing). I really like how everything else blends and works together in At Last and A moment to Breathe and how you brought your melodic content from the first track to the other tracks(that's something I see others tend to not do and you did really well with this it was very satisfying hearing how you used the melodic content throughout). Good work :)
