I really like the collage, but I think some of the individual pictures are actually better on their own.
Like for example the picture of the pitcher plants. You posted it alone awhile back and I thought it was quite good. The mirrored crane/heron is also quite striking and the perspective of the paph in the top left corner is also very interesting.
My 2 cents would be let some of those speak for themselves. Plus, I just love the pitcher plant pic!
