In Festo Transfiguationmis Domini Nostri J. C.Domini Nostrils may cause offence (though I smiled, briefly).Not sure what you are after in terms of feedback. Not bad for sightreading, but surely a few more times through wouldn't have hurt for a "hey guys listen to this piece" type performance?
using the latin I learnt from highschool, does 'In Festo Transfiguationmis Domini Nostri J. C.' mean, 'in the holiday of the transformation of our master jesus christ?'
