1st of all I want to say I like it. The feather being off center is a good touch. The overall scenery is good. I like being able to see the rocks/pebbles at the bottom of the lake. Fairly clear water. I also like your DOF. The only thing that is just not doing it for me is the brightness of the shot. The sky is too bright and that bleeds down into the water. Good job. Happy shooting.
I'm really struggling to get my head around this one - clever use of forced perspective, but the pebbles showing in the reflected (?) part of the feather confuse me. Definitely an interesting shot.
