i really like the first song so far, i think the only thing i would have done is add a bit of a harsher bass nice and quiet down, seperate to the electric bass to help ground your chords a bit more, as i find they are sometimes clashing with the melody as there is a lot happening in that upper range. Not to say its bad, this could just help flesh out your concepts a bit more because this is really cool
I understand a bit what people are saying about the second song not fitting, but i still think its pretty cool nonetheless! I think if you wanted to connect it to the other songs a bit more you could experiment with instrumentation and find some more through lines, or use melodies you use elsewhere to help remind you "hey!! same story here!!" but it still has a ton of character, and was enjoyable!
the third one was super playful and fun, the piano was really well done and reminded me of undertale haha, no complaints it was super cute and fun
Walking in the seagrass is a super pleasent listen, very relaxing and I could absolutely see this one in a game, and the melody in those strings feels really well placed, i like how you experiment with dissonance and pauses in this one especially, Maybe tone the reverb down on the lead violins though because it can muddle up the sound a little bit especially when its a sole focus like that, overall nice work tho!
