It was hot today. Needed some fresh air after lunch. Found this white dead nettle (I think). Didn't noticed the yellow guys (or girls) before I saw the photo on screen.
Nice macro work to get the detail of the thorns and the fine hairs. As you mentioned, imperfections in flowers are hard to avoid. I keep searching and searching for flawless flowers to keep from having to do so much cloning and healing brush work in post processing.
