Hi Mike, as you have asked for critique I will give you my honest thoughts. First of all I would disagree with Steve and say this is far from beautifully sharp, there was obviously a lot of movement going on at the time which is fine on some points of the subject (motion blur) Actual sharpness of the important part the head for example is not (soft). Not sure how far away you were from the subject so this might be a large crop even at 250mm. In saying this you have still captured the moment, you have a good surrounding but the subject could have perhaps been moved over to the left and given more space for the way it is facing. If the background in this shot is typical of the stretch of river then it looks like it could be prime Kingfisher territory to me.
