Welcome to your first OST jam! I've been around the block a few times but I'm looking forward to hearing what you put together.
Eclipse: I see you have some really excellent sound libraries-- this track sounds utterly beautiful. I always caution against the repetition of one line while instruments are added to/taken from it (a sizeable chunk of the soundtracks I hear ultimately boil down to that.) What makes this track acceptable in my mind is that the entrances of instruments don't always align with the start and end of the repeated phrase. In the case of the staccato strings, they actually come in on the 4th measure of the phrase.
Soul: love the reversed audio bubbling around. The entrance of this lush cello melody is divine, and I enjoy the tone shift. A beautiful little clip that moves.
Lover's Reunion: I can't lie, the first ten seconds actually gave me chills! What a delightful, delicate little piano-celesta gesture! The cuckoo clock is humorous, and the clarinet over plucked strings in 3/4 is another classic way to symbolize something whimsical. The interplay of woodwinds, and the constant passing-off of the melody is perfection. Another favorite moment is 1:05, when the strings join the bassoon briefly for the melody. In fact, delightful moments keep occurring faster than I can type. I think you've got it figured out...
The Medieval Battlefield: is that really you singing? It sounds like it could be the EW WordBuilder-- or you just have an insane, insane low range. As a baritone myself, I'm envious of this. How did you make that recording? It's so cool and ominous. I love how this track balances sounding almost haunted with having this majestic, somber feeling-- the souls, sad to be dying, perhaps...
The Child: the addition of the heartbeat is a creative way to add emotion, but the piano and string combo is emotional enough! This is the most cinematic of the tracks thus far-- it perfectly captures the feeling of saying goodbye. The icy harmonics are another excellent addition. The pulsating piano certainly sounds like it's imitating the heartbeat as they both fade.
To Safe Thy Soul: yes!!! love the energy that this track sparks. When the melody repeats, and it's echoed by an oboe countermelody... loved it. My only complaint (possibly my first and only complain so far?) is that the opening is so intense, but it gets more subdued as the track goes on. Around 1:45, we almost seem like we're picking up again, but it once again fades. This big, beautiful flowing lines are welcome, but perhaps a percussion instrument would have picked things up a bit. Still, such gorgeous and incredible music!
A Second Chance: I love the return of the opening theme. The solo strings are wonderful (Cinematic Studio Solo Strings, I think? I use the same ones!)
In all, I am glad that you fleshed out your story so much. This soundtrack is incredibly polished, and despite living in a traditional orchestral world, the reversed audio and genuinely exceptional writing keep it from ever sounding remotely mundane. This is undoubtedly one of the best I've heard so far. I can tell you've put your heart into this, and I really hope you'll stick around do these jams again and again. Beyond exceptional work-- keep writing!!!
