Interesting photo.
The detail is very nice in this. The veins going thru the dragon flies wings. The texture of the eyes is very nice, the textures thru out the photo are quite nice and evenly captured thru out the image.
The use of vignetting really works for this photo, and the shallow depth of field is very nice, and helps to highlight the dragonfly as much as anything can.
All in all a very detailed and nicely composed photo of this interesting creature. One hopes to see more photos of this nature in the near future. Nicely captured photo.
