HA!
its funny how differently you look at an image when it has a caption attached to it!
If i was to comment on any of these critically it would just be on the last one and only that a little bit more space above the thing sticking out of his head might have been nice!
What do you have in the background of the images?
i notice they are almost always vivid colours or at very least not the greenery you might expect
and how on earth do you get so close to a fly without it buggering off??
Very good shots! I love the wasp in the last one, although I agree with Hamish on the space above. But the sharpness and colour are outstanding, well done!
