I applaud your efforts in finding something truly aromatic. I think this would work a little better if it seemed more "fresh". A little steam perhaps rising from its pungent folds or just a little less "baked" looking. The lighting seems a little harsh. A diffuser held over the ripple-back brown trout would even it out a bit and reduce some of the hot spots on the grass.
Pee Yeew! You caught odour, stink, pong, smell, really well. Topic is scents and aromas which, to my understanding of the subtleties of English are pleasant. Not too much special in the image but I liked your title.
Cow pies really don't smell that strong...unless they are fresh of course. Was this a joke? I would guess so. It's not really appealing, unless your looking for something to burn in the campfire. Light is a bit too bright also.
Unquestionably aromatic. Would like to have seen enough light on the subject to remove the distracting shadow on the right side. Not terribly visually appealing, and not something I would hang on my wall, but it sure meets the challenge!
