I love the way the veins of the leaf actually look like they have 'blood' coursing through them. The interior workings of a leaf are quite spectacular. As a side note I did have problems getting this one down to the 150kb limit. I wanted to show a non resized crop from the original, but I also wanted to show some of the structure of the leaf. Not possible with all the detail, oh well, a compromise was reached with a resize to 78% of the original, an acceptable size of picture, not too compressed and some leaf structure!
