Love the contrast of colors... nice vivid colors... my only nit would be to use a diffuser to tone down the light when shooting, just personal preference... otherwise a wonderful shot!
Beautiful colors - not much else to say other than that I would probably burn in the upper left corner to match the darkness of the sky in the upper right. I suppose you could even pump up the blues just a tiny bit.
Reminds me of a shot I took while in Amsterdam. I love tulips and you really set up a great shot of them here. Wonderful, vibrant color and a unique perspective.
PERDY!! Love the perspective as if you're a bug on the ground looking up. Tulips are glorious and when you take an image en masse - it really has impact. Nice one.
