Nice pose, bg and near perfect HA. TFS

Great action captured. I like the BG. I think a little more room on the left would improve the comp.

Chas:

I like the action, sharpness, exposure.

I am OK with the comp. The attention is so directed down to the right, that I don't feel it is crowded on the left. Personal taste in this case I think.

Terns are such elegant flyers and divers. Hope to see more.
