I have come back to look at this picture close to ten times now. Excellent work here, thanks again for posting stuff that really exemplifies this craft. The macro work here is something to strive for, I really need to invest in a macro lens for the digital SLR. Damn I wish I could get that kind of result on a regular basis.

I know! The lighting is exceptional! I try but my lighting is wrong and my eyes are not as good as they use to be. Yes, something to strive for..
