oh! so simple & lovely in its simplicity! nicely done with the "imperfection" of the hole in the sand dollar (& you are SO LUCKY to live near the shore) :) 7
Crop a little tighter, removing some off both top & bottom, to fill more of the frame with the shell & the rippled sand. That part of the photo is lovely.
Great shot. The crop is just right. It gives the artistic flair that really takes this shot to another level for me. Too close a crop would have made this image fairly average, but the room for the background to fade way is just right. Great job.
