Hi Dale great composition, perfect timing and the whole image just works oh so well with all the content, but agree with Hasseb, the image is not sharp sadly. A bit more DoF perhaps and certainly SS, as you had plenty of ISO to hand I feel. A great moment to witness too, just love these bears!!!
Such a cool pose and look here. Would love to photograph this myself one day, Dale!
Have to agree with comments above, think the SS was a tad low for the head movement?
