My First Day with Macro.

Today was my first day really trying to shoot macro photography.  I am finding out again that I really enjoy working with available light, which did make things a little more challanging today.  So far I am happy with a few of the images I captured today, however, I realize there is much much more room to grow in this field.  I used my 100mm Canon Macro lense to capture this image.  Please, if you have any tips on macro photography I would love to hear them, as this is a new adventure for me.  Thanks!
