Each of these images is fairly great as a stand alone...and I thought of posting them in this way...but instead constructed this Tetraptych (btw this is the correct word for this).
I'll be the nay sayer. The shots are good, but there is no presentation. There should be some type of border, and me, I'd leave the fourth shot out. The sea weed isn't doing it for me. There's a reason that so many people construct the three shot panels, it just works. I hope you don't mind, I'll put a 3 shot version in pending. Delete it if you wish. davev
