Donaghadee Harbour

Today I shortlisted my images down to six and even then I could not decided which image to select.  So I have uploaded two by way of an extra image.  Your job is to tell me which one I should have selected as the key image and why.  That would be instructive.  The two scene are the boy jumping off the harbour and the second a young boy fishing off the end of the harbour.  The water is quite deep and according to the boy who dived in its very cold.
