"Sibling Song" is gorgeous, really lovely instrumentation here. The staccato strings in "The Docks" give that feeling of a busy city area. Switching to pizzicato strings and a mallet lead does a great job of transferring things to that nighttime vibe. Bonus points for including the time-honored fishing minigame theme. Nice work there.
Overall, your soundtrack has a very soft yet vibrant feel to the orchestration, reminiscent of a Studio Ghibli work (Nino Kuni definitely comes to mind) or Dragon Quest. Everything is very subtly emphasized, no instrument ever feels overstated or out of place. There's a very smooth and clean sound that is masterfully done. My only critique would be overall volume, it does feel a touch low. I realize that could be a bit of a challenge though with the lower velocities you were bringing out in the instruments. Regardless, excellent work overall!
