Sanctus, Op.30

Try the interactive tutorial, or download the Sheet music here: musescore.com/...
This is a choral piece based on the Christian liturgical text of "Sanctus", and is the second choral music I have ever written. Throughout the piece, I have utilised drastic modulations to create an "ascending" feeling. Hopefully, I managed to hit a balance between dramaticism and musicality this time. All comments are welcome!
Original text in Latin:
Sanctus, sanctus, sanctus Dominus Deus Sabaoth:
pleni sunt caeli et terra gloria tua.
Hosanna in excelsis.
Benedictus qui venit in nomine Domini.
Hosanna in excelsis.
English translation:
Holy, holy, holy Lord God of hosts:
heaven and earth are full of your glory.
Hosanna in the highest.
Blessed is he who comes in the name of the Lord.
Hosanna in the highest.
