" Out of the Blue" meets the Square Crop challenge, which is always a great way to start a challenge. Also finishing in the upper fifty percent is always good in such a huge challenge.
The image itself is very nice. I personally have tried a couple of times to take pictures of my fish (they are only freshwater) and bot is it a challenge in itself. So I really do appreciate the work you have done. I think the focus is good, probably without glass between the camera and the subject the clarity would be stronger. The most interesting thing I notice is the clear fins on the tip of the tail and on the fin. The background blue is very strong and I really like the depth it gives to the shot. The contrast between the fish and background really allows the viewer to focus on the subject.
Overall with the subject that you choose I think you did a great job. Keep up the good work!
Something about the composition of this shot feels awkward to me. I like that you gave the little guy enough space around him, but it feels too static with him placed right in the center. Perhaps cropping so he was just a tad more to the left and up, like he's swimming into the shot with more space to go? Either way, it's a cute shot of the little guy.
Cool fish. They are fun to have. The photo is a bit plain though. Lighting is always one of the first things I see, and what sways my voting one way or the other. The other technical aspects of the photo are well done, but just work on the lighting. Both in-camera and during PP.
