Another Christmas Mash-up

For my 2nd submission to this year's Christmas Music Event I come to you with yet another mash-up of two Christmas Carols!  "God Rest Ye Merry Gentlemen" and "Jezus Malusieńki" ("Little Jesus" in Polish).  I have input 6 stanzas of each Carol here into the score.  I once again wish I had Cantamus as listening to both the English and Polish lyrics at the same time would really enhance the listening experience to those who speak both languages.  The piece starts off with a 3/4 variation of "God Rest Ye Merry Gentlemen" and then follows a stanza of "Jezus Malusieńki" before the Carols are combined together at the same time in various different ways, some of which are slightly polytonal.  I've been told that the harmony reminds of the English Renaissance in some parts, but let me know what you think!  Thanks for listening and I'd appreciate any comments, suggestions, critiques or just observations!

P.S.:  Here is my first Christmas Mash-up that I submitted earlier for this years Christmas Music Event:
