Really cool song! Feels ethereal. The intro is great, because I don't hear a time signature at all; I just feel a nice flow of notes without any sense of time, fitting the theme. From 0:43, I feel the 5/4 structure (my favorite time signature!) in there. You use it perfectly, dividing it into 3+2, with the "3" divided into two notes (of 1.5 in length), and the 2 divided into 2 (of 1 in length), but also into 1 (of 2 in length) or even using triplets! Great sound, very calming, and incorporating my favorite time signature well - very nice entry! :D
