Hi Kib,
I took a listen to your Christmas one. As Kidkboom mentioned, your English pronunciation is very good. You are rushing a bit. A couple of words that hit me are:
"was always" those to words together don't come out just right. I can't tell if you are mispronouncing the W in always or if it is something else.
on the words "breakfast" and "everything" it sounds like you are rolled the Rs almost like an Irish would sound
yet on the word "presents" you don't pornounce the R hard enough.
