Nice shot, contrast and exposure well done, but almost wish the whole shell was in focus, it is not like there is a distracting background where you would need a shallow dof.
I absolutely love the DOF and the detail you have preserved here. Possibly the strongest entry in the challenge in terms of meeting the challenge. Subtle colors strengthen the image. Great job. Among my top picks.
I like your frame, DOF is good, Something about the placement of the shell is off to me, but i'm not sure what. Possibly it would look more complete if the shell was cropped slightly at the bottom. I think our eyes are used to seeing a base either real or implied under an object. JMO.
Beautiful. It has a tiny bit of softness - probably due to the bright light. This is stunning. The shallow DOF is good too. Great detailing of the intricacies of the shell. This may be my fav of the challenge. 9
Stuff that white space to the right - it really would stand cropped close, no? You've let me down there because I love this pic apart from that. Nature is amazing isn't it (my God we are part of nature too!)
