Hi Layla,
Yes, you are right; New Zealand is a beautiful place but being a Kiwi, I would say that anyway.
Even though it is hard not to make a great landscape photograph in New Zealand, there are still things we can do to improve most photographs.
In this instance I notice that this sky is clear and rather bland looking; in the grand scheme of things it contributes nothing to the photograph. The question is, do you really need all that sky?
Most people assume we need to have a sky in a landscape photograph but that is just conventional thinking. Delete the sky and all of a sudden the viewer is left wondering how far that horizon can stretch for; are there other islands out there and what might that sky look like if we could see it?
As they often say, less is more and I think by removing the sky you can make this photograph stronger.
There is only one other adjustment that I would make to this photograph now; go to the curved panel and just pull the middle inwards ever so slightly. This will darken up the tones in the image and add more overall depth to the photograph.
I hope you get to visit New Zealand again soon.
Cheers,
Anthony.
