Damn dude, you really don't give one much to really work on here. Lemme see if I can get something out of this already awesome photography hehe.
The plant / flower to the far to the right there close to the boarder. If that woulden't have been there, more negative space, I think the photo would've more dynamic in terms of depth and structure. Don't get me wrong here, that particullar flower really adds to the depth and provides good focus to the shot, just that without it the composition maybe would've worked even better than it already does.
The string of web that leaps across the shot to the bottom right corner works perfectly as the leading point of the shot to create an interesting read with the eyes.
Very good shot mate, really great!
Sorry to make a double comment, but many to not know the difficulty in taking a photograph such as this and take them for granted that anyone can do it. that is until they try. you have a good eye.
