I think the second one with a little bit of color in the flower is more interesting, but the central framing hinders the "pop" potential. Perhaps a tighter crop applying the rule of thirds might make the difference.
Not that I am any expert, I get a lot of advice from this same forum...
Still a bit vertically central, but number 3 looks very good. There is a bit of wasted space behind the bee. Get rid of that and I reckon it's a winner.
I like the mono background mate, it really draws the eye to the bee and what it is doing.
