I think they are amazing. I know it's insanely difficult to get a job for National Geographic, but some of these seem worthy...you should check that out if you're interesetd and see what you would have to do if it were possible
The cat is great the eye is spooky and the shilhouette against the sky is lovely. The light and landscape shots are beautifully executed....and the long shutter speed water shots-WELL DONE!!! And I don't think it is the camera , I think you've got talent !
Woooow! Is that your cat? He doesn't even look real. Amazing. Love your silhouette as well. It has a very good feeling for me.
