Hi Fabs,
Without a side-by-side comparison, I don't see much difference (except in the beak area) between the two posts. (I was flipping back to the Avian thread but my recall needs some assistance!)

I like where you were trying to go with this one, Fabs, but the horizon line seems to me to make it look like the bird is on the water rather than above the water especially with that large a "reflection". It might look more realistic if you could constrain the reflection to a smaller part of the water beneath the bird and not have reflection right out to the horizon and bottom edge.
