Piano-centric pieces will always reign supreme for me. Echoes of Yesterday kicking things off is great - it has an almost pensive tone to it, offset by the faster section mid-way through. Great articulation in the playing here; ebbing more on the side of softer and more gentle while coming to the front when needed.
Moments of Clarity is befitting of the title as this piece doesn't feel quite as pensive as the last, but instead has a more sombre and progressive feel to it. A little more definitive as a whole. Again, kudos on the articulation here. Great choice of chords as it moves on and the gradual reduction in the lower register as the track comes to a close is a nice touch.
Journey Within is a solid one to finish on, and the mood of this track is a little hard to nail down. Not quite as pensive as Echoes, but perhaps a little less definitive than Moments of Clarity. It has a heaviness to it, more of a dawning realization and early stages of acceptance. I think of the bunch, Echoes is my favorite, but as a whole this is really solid!
You mentioned in another comment that you would've liked to add some strings and I think that would have been interesting - I could see it elevating the arrangements a little higher, but they are fantastic as is. Great work with these. :)
