This is really beautiful, Jordi. It's got that wistfully sad undercurrent, and the Greek lyrics are interwoven throughout the melody very well. I don't personally know much of the Greek language, but Kyrie is certainly familiar to me. Very nice timing on the lyrics and your harmonies at 2:34 are absolutely lovely! There are a lot of subtle nuances in the song, including the way you incorporated the stereo field into your background choir. My only real complaint is the the song ends too soon. :D
Good luck in Round 3, my friend.
