Wonderful job. The mixing sounds professional and each track has a distinct identity. Also, in my opinion, every song executes its purpose.
"A Short Rest" - serene and relaxed, a perfect fit for some... well, rest between the more intense scenes, creating nice pacing.
"Suspicions" - my personal favourite. It is still relaxed, yet there is so much more tension. The ticking sounds are a nice touch, almost as if there is a bomb which will explode any moment ("You're not safe though, as danger could show up at any moment to ruin your revelation. Do you hear the timer?"). Then the section with short strings brings in that sense of wonder and curiosity. 10/10
"FIRST ENCOUNTER" - as many have already noted, this is a banger. Professional and engaging. Yet, for me personally, it feels a little bit more like a miniboss / boss fight.
You did great!
