Well Malley
If its any comfort- at least you have a shot of a seahorse in your portfolio.
If I found a seahorse in a setting like this....... I would've been thrilled!!
I love the setting, and the way you can see the sea horse's tail wrapped round the pole.
IMHO this shot has so much potential to offer and you could've tapped into this potential right there and then- but it takes practice to do this- and-we are all still learning..one way or another. If I was taking the shot, I would've gotten closer, poured on a bit more light and waited until I could get the sea horse's face nice and clear- at a minimum.
Then I would've experimented with strobe angles....making sure of course...that the little guy wasn't flashed out of it!
If it was me personally (bearing in mind I am my worst critic) , I wouldn't enter the shot simply because the seahorse's face is looking away from you. There is no eye contact with viewer, so the viewer/judge won't make a connection.
However, my man, as many here will attest- judging a photo is all on the day!
Im sure others here will have their own views on this 2.
Good luck
