Nice sharp, and well detailed image Gigi. For a better composition it would be best to have it over to the left a little more (off centered) as if it were reaching into the rest of the image.
"Knowledge is knowing that a tomato is a fruit, wisdom is not putting it in a fruit salad." Miles Kington. So I'm sure you'll have both knowledge and wisdom enough to go over and see My Gallery.
Gorgeous capture of this lovely thistle, such wonderful detail and colour. I would have had it off to the left more showing more green on the right, drawing your eyes into the scene. It's still a Fabulous shot to me, such outstanding detail
