This was a pure and simple back-lit photo because the background was in deep shadows and I didn't want to blow the highlights the background goes to black. Nothing tricky about it.
When I first saw this photo I skipped it, I couldn't decide what score to give it, or what not. Now I'm back, and I feel like I have to explain why I'm giving you a 5.
Whereas the quality of this picture is good, it's sharp and the colours are nice and I really like the composition, I'm not going to score this higher than 6.
I am not saying that you have taken this photo in a studio, or that you haven't, I'm saying that to me this just doesn't feel natural. The light doesn't seem to fall from a natural angle, the background isn't really a background that just appears in the nature, but I also know that there are so many ways to get around this problem.
For me, when I read "In garden and field", I don't read "Must be garden or field visible in the picture", but I do take it as "use the natural light and what the nature brings you and make the best of it". I don't see this in this picture, and therefore I will give this a 6.
the way you've taken this or processed it really makes this LOOK like a studio shot. Me I usually love the deep, deep greens that are missing from this picture and go along with this particular flower (one of my favorites!!!)
again im sure you're getting hammered as it looks "studio" but i completely believe it is outdoors and well processed and executed. having said that, im not crazy about the composition i think i almost would have liked to seen a more shallow dof. still nice enough for a 6
