Lots to love about this. I honestly didn't expect to like this as much as I did. I like calm orchestral pieces that pack a bit of punch like yours. They're really dynamic and don't let you get bored. Think "Spring Rounds" from "Rite of Springs" (although that second half of that song does get a bit too dynamic for me... I can appreciate the experimentation and storytelling, though.)
Song of a Forgotten World was pretty well composed. The soft piano part alongside the strummed mandolin, followed by those choirs... Makes your mind dance. I like the subtle switch to the harp in the middle, it's also played very naturally... You seem to have a good grasp on velocities, and such.At 1:18 on track 1, the chord progression took a developement I did not expect, gave me goosebumps.
Frostbite Fissure was absolutely amazing, I really felt a fairy tale, mystical vibe to it that I don't often hear captured in songs, like genuinely. I did think that the choirs in the background playing the Bond motif was a tad strange (probably unintentional, it's just impossible to listen to this without thinking of the movies, but it was still cool. The way the bells prepare the arrival of the strings is just so heavenly... The only thing that brought it down a little for me was the little crackling that can sometimes be heard in the background, which took me out a bit. I think it might actually be the bond choirs, actually... I chalk it up to your plugins instead of your ability to compose, but it's good to know for the future. If you ever wanna make another theme for a crystal cave...
I know you don't want us to be kind, but.. I really don't have any grievances about this lol. Extremely impressive for your first jam, and with only free plugins?? Like damn. I'll give you this: some of the instruments, like the choirs, don't sound super realistic, if that was the intent.... But it really wasn't a huge deal. You might flourish even more if you invest into paid libraries.
High grade from me!
