Thank you Kerstin. Regarding the blur: Yes that's a problem. Because the leaf is not entirely flat and with a distance of only 2 or 3 centimeters some areas get blurred. Maybe I should have chosen a greater distance. And get a good macro lens... I'll try to improve. Thanks anyway for stopping by.
It might be a tad blurry but the colours are wonderfully rich. such vibrancy to this shot Martin. Maybe a reshoot under same conditions but with a slightly greater distance? you can always crop a tad next time to retain final image size.
