#1 looks like a beautiful place, but the composition doesn't do much for me as there's too much going on, too many trees, too many reflections. Perhaps cropped a little different to showcase some of the reflections might be more interesting.
#2 is a very nice subject and great colour, but I would have liked to see the whole tree. The shadows in this one unfortunately overshadow the colours of the tree.
#3 I really like this one, but the sidewalk on the lower left and other building at the top are a little distracting.
#4 Beautiful colours and contrast. Good work with a foreground to showcase the background. I would have had a little less of the plant, perhaps just a little on the left with more ocean.
Thanks for sharing.
