mm70 - Sharp

Thought I would try some of the challenges this week, just to keep it interesting...have only done a few of these in the past but it's good to try new things out...
This is my take on this week's Mono Monday challenge which I believe is "sharp"...I've had this macro lens for quite a while but I've never really got the hang of it...still think I need a bit more practice to get the focus and depth of field just right...
