Welcome to Photography Ireland.
I prefer the second, though I find the flower in the background too distracting. The tortoiseshell is almost strokeabke!
Re three, if the fuchsia were to hang vertically I feel it would improve the p[icture. Others may disagree, of course, such is PI.
#1 is not so attractive, all down to the butterfly and the flowers not being in their Sunday best. A square crop on this might be good.
#2 is nice. Shame about the rear flowerhead being a bit tired, but none-the-less still a good photo. You got a great angle there.
#3, I guess because it is in the shade it is too dark to be outstanding. Pixelle could be on to something as well…
Keep up the good work & post more soon, summers nearly up for honing your technique for flowers and bugs.
