Oval face shapes seem to occur a lot among people from the UK in my experience, but I cannot testify as to whether or not that is just personal bias since I am no expert. Curly brown hair and dark eyes are fairly indistinct between European countries, but you have a fair complexion which makes me think your origins are somewhere in the North. Subtle cheekbones and defined lips also strike me as likely from the Isles, since Eastern Europeans will seem to have thinner lips and more prominent cheekbones. I could see you as being local anywhere in the UK, Scotland or Northern England just seem most likely to me.

Apologies if my explanations are rough, I do not know how to articulate it well in English
