Excellent image! Liked the blue sky bg and the thin line of cloud at the upper part of the frame. Because they look very thin and have slight blackish touch to them(esp in the top left corner) they are adding a great mood to the image. The bluish touch in the central and bottom right part is imparting a soothing feel to the whole frame. The light on the plant is just fantastic. To be frank, for me the image is made without the snail itself!
But I see a small dot in the right side space of the snail. That is intriguing a bit. Is that a dust spot or any flying object? :-O
