The second shot is way more noisy than the first - ignoring the blooms themselves and looking at green leaves in the background, which are of course out of focus, reveals sharp black spots in detail to me.
Was the second;
a significant crop?Or a combination of those?
underexposed in capture?
shot at much higher iso?
On the first, at the top and left; there's a petal and leaf sticking forwards into the sharp zone of DoF, I'd suggest cropping and/or blurring these as they distract.
On second, I would also clone out the sharp bit of foliage protruding under the lower edge of bloom, as it 'grabs the eye'.
