My gut-impression here is that you ought to immediately go back to your first impression of the scene, and improve upon it.
My main (and, really, only…) objection to the first scene is that you are completely missing the highlights on the front surfaces of the leaves. And, one of the key reasons for this, is that the background has this huge bright-spot(!) that is stealing the entire show away from those poor leaves. (They just don’t stand a chance.)
So… let’s take a look at that real-world photograph kindly contributed to us by “Wefyb.” Yea, indeed, I think this is no accident. In this example, the backdrop is both very soft and subdued (thus: not competing with the subject in terms of brightness), and definitely blue (thus: not competing in terms of color family). Your current backdrop choices unfortunately do both. Your subject is fairly devoid of highlights, whereas your background is presently full of them. Try reversing the two, as the professional photo offered by Wefyb did, and see if the same magic does not happen for you as did happen to that photographer.
Consider: both of your interpretations so-far are suffering from the same malady … the background is competing with the subject, and winning. (Kindly do not take my words to heart, as being “too” critical or as stinging “too” much, for I surely do not intend them to be so!) Give your poor subjects a fighting chance. The human eye is always attracted to the brightest area and to the sharpest contrast. See to it, then, that these areas are your subject.
(Just to be clear: each of your two very-different concepts … express two entirely-different, and very-good but IMHO needs-improvement … treatments of the subject. But, again purely IMHO, both of them suffer from the same avoidable fate. Study Wefyb’s professional photograph …)
