This starts off really well - it creates the feeling that someone is about to do something they can never go back on. At about 0:33, when you introduce more instruments, it makes it feel as though they are entering a land that they do not know, and are about to explore it. The building of the music between 0:55 and 1:00 is subtle and brilliant at the same time, and it just washes over you at the climax at 1:00 and 1:31.
You create an atmosphere of adventure and success. It does this very well indeed, and by the end you feel you have followed a character from leaving their home land to successfully establishing a new place to live. Between 2:45 and 3:00, you have also created an effect of homesickness of this character.
Very well done indeed!
