Self portrait by the sea

This hopefully won't come across as too vain, I decided today's photo was one I took this afternoon, by the sea, on the beach in Barcelona.
The sunglasses are ones I recently bought & have had a little bit of buyers remorse over (this is a rare emotion as I seldom shop) what do you think of them? Too loud? Look good?
Either way, this picture is a happy picture as I felt happy and warm when I took it
