It's fine. There is a very slight trace of an accent, what I would even call a "charming accent," but it is barely detectable.
My children have been taught by elementary school teachers with stronger accents than this, and it was of no concern.
In the United States we are used to hearing varieties of regional accents and traces of foreign accents (because of ethnic enclaves).
I can't identify the accent. It sounds European to me, and not Spanish, Italian, Portuguese, German, or Dutch. Not Chinese, not Indian. Peachey suggested "Russian," I was thinking perhaps Swedish or Danish.
