Mike, I'm wondering why you chose f13? It appears he is pretty much on the same focal plane at this angle - I bet you could have got a way with a wider open aperture and not retained so much of the distracting details in the BG. Any thoughts on that?
As is, I would definitely go with a much tighter crop as the BG really pulls my eye away in almost every corner.
Mike, I agree with Julie's excellent critique. With bugs I would suggest getting as close as possible which will greatly help minimize the BG. Looking forward to your next one!
I was having trouble getting the whole bug in focus so I bumped it up to F/13 -- nothing looked sharp enough to me. I also wanted to avoid cutting all the leaves off of the plant it was on which is why I didn't go all the way to 300 mm.
