Vision: I gave vision 5 stars. This is a great shot, clear and close, of this species of mantid. The fact that it's on some tree and the background is black gives it a more natural appearance, rather than if it were in your hand or in a container. The black background also shows off the mantid's detail and its' coloring, which is great.
Originality and Technique: I gave originality 5 stars, what with the way you arranged things (tree, background, camera angel, etc).
Impact: I gave 5 stars, because of the reasons above.
