Thought this was interesting - tricky to photograph though because of the cylindrical nature of the scene. DSC02275 by mike mountain, on Flickr DSC02279 by mike mountain, on Flickr
Nice find. It is tricky. Standing back to take the shot (and using a small aperture) and then cropping aggressively might help. Also, if possible, change position and angle of attack to get the main steam more parallel to you. Or perhaps you did all that anyway?
I was over reaching as it was, leaning right over the very next photo was nearly a close-up of the middle of the rose bush! I found, in the last few days, after frustration with lighting and bugs in hard to reach places that my biggest nemesis is a sudden gust of wind or breeze. You've just nailed the right composition. Focus is wavering in and out of the sweet spot. Arms are beginning to ache. You go to gently squeeze the shutter.. and ... Woosh! The damn wind.blows everything out of kilter and the bug flies away.
