hello dear, are they really snail shells? at first glance I was convinced that it was the final part of the screws that are used to nail the boards ... you took some really beautiful photos ... it would be nice to be able to print them and hang them on a wall at home ... really very suggestive! it seems they have a soul! How old have you been as a photographer? I really like these photos of yours. I want to follow you to see your other shots. I wish you a good evening to you and your family and congratulations again
