You've successfully put the center of interest on the habitat, where you intended. The bird is a contributing element, but doesn't grab attention. Well done!
This is good use of the rule of thirds, but the overall quality of this image is not as high as it should be. Perhaps it is a combination of color and lighting, but the reeds detract from the image rather than support it. This image has great potential though.
Doesn't really say chaos to me... bit too much detail for the eye to take in though. I feel that the bird which is quite interesting should be the point of focus, but this is not clear.
