Dear Hanny,
thank you for your designs! We liked the concept of the sea and big sun. The sea only looks a bit like a moustache and unfortunately the Dutch beaches do not have palmtrees. With regard to your other design: the sun is very charming and gives a positive feeling to the logo. The dune only looks a bit like a mountain with some snow on top of it.
Hope this is helpful and thanks again for your entries!
Kind regards,
Patrick and Lotte
