Beautiful! What part of the Everglades?
From my perspective your images are very grainy. The focal points are good. However, some images you are slightly out of focus. Take your first image. Very nice but the three bugs in the left foreground are slightly out of focus. So I would say if you got a nice crisp of those bugs plus the ones on the stem with the background the way it is, it would make your picture pop! Plus if you have a photo editor I would 'pop' the yellow lines on them.
The second picture is good, along with the alligators. The black and white alligator is a bit bright on the one side.
