Valildated or not, that hand just looks out of place and well to be honest, looks pretty bad. I think the idea is good and I really like the movement of the ducks, but that hand drags this shot way way way down. Anyway, still good though but if you would have had a normal looking hand and perhaps a little less colour noise in the ducks it would have potentially been an 8 or a 9 from me even, and I don“t give out many of those so keep it up.
The hand and sleeve seem to be the recipient of the duck's wrath, but it looks like it was pasted in from another image as an afterthought. The high saturation of the grass and the ducks implies that they are the intended subjects, but the drab, flat looking (glowing) hand which lies at the focal point seems anticlimactic.
I like the blurred ducks....the grass is very green and looks lovely. I have to say that the hand is a little distracting, though I see what you were going for. I wouldn't want to be attacked by that many ducks either!
The picture of the ducks looks interesting but the weird hand with glowing edges doesnt seem to belong to the same photo and so the ducks appear to be "savaging" something under the hand, perhaps this was your intention?
