Very cute entry and nicely observed. The DOF is a touch too narrow so I would have gone for a larger aperture to retain all focus. Since there is no movement captured this would be fine provided you have a steady camera.
What in interesting icicle formation - it makes for a striking image with a composition focused on lines - four "rows" across (water, black shadow from the underhand, icicles and solid ice) plus vertical columns from the icicles themselves. My only preference would be for more even lighting left to right.
What a very interesting capture. Very cool icicles and what an awesome find. Its not the most compelling picture, but it is quite intriguing. Good job 7
