You are right Ken, it was probably sharpened a bit too much. I have to change that, although I can't do that anymore now because if I would change it people would think your comment is a bit strange!
It was shot in the wild, no flash. Your comments are realy appreciated, feel free to comment and have critique and suggestions. I like to write a bit about my thoughts about the image! I agree it would be more obvious to let the flower stand out but in my opinion the image can than become a bit one-dimensional. Since these flowers are so eye catching (that is what they are designed for!) they become so prominent in the image that they blast away everything else. So I actually like this somewhat concealed flower!
What I like about this is that all the other elements become as important as the flower. Also non-subjects like shriveled strands of grass, out of focus dots in the background. It is also a bit messy image which I prefer to a more glossy one because it is different from what you would expect. But feel free to disagree. It is just my humble, somewhat weird taste, and I am also just thinking aloud here.

My aim is never to make as beautiful pictures as possible but to surprise myself with a 'different' image, something that I have never seen before. Something like that, does that make sense?
Dave, you are right, it is Echinocereus dasyacanthus, the Texas Rainbow Hedgehog, Yellow pitaya. Not a real coincidence because I was in Texas a couple of weeks ago. First time there and it was great, in the Big Bends area. I was just at the beginning of the flowering season so most cacti were not blooming yet or just beginning.
