For a first attempt at composing an original soundtrack, you put in some serious work. Expansive list of tracks covering a fair amount of genres, without anything coming across as being a copy of another.
Really nice arrangements and a good use of a variety of instruments and voicings. I think that An Altered World is one of my favorites of the bunch - has an air of mystique to it without leaning too heavily into being quirky. Managed to have everything sound cohesive as well, which is impressive given that it spans a few different genres and styles of writing.
I don't personally think the track lengths are an issue as they could always be looped or iterated upon again if necessary. If I was to pick one thing to nitpick, I think I'd go with saying the drums throughout can feel a little dry and buried at points. However, I'd like to counter that by also saying that the guitar work was tasteful and implemented really well - never overpowering the mix, sitting right in where it needed to and belonging comfortably.
Great work!
