The markings certainly look like a Welcome Swallow Brian and I presume the characteristically long tail feathers are partly obscured by the leaf. Are you confident of your colour temperature as it looks very blue.
Google up Welcome Swallow and look at the colouration. I put a camera raw eye dropper on the chest feathers and it improved it to my eye but the back of the neck still looks blue.
The crop is a matter of taste but there is a lot of space behind the bird. Are you allowed to work on the eye a little?
Is it a "nature"with specific rules? This will determine how much work you are allowed to do.
The only other comment from me is "where does your eye go?" Mine goes to the bright red leaves. Again a matter of taste and the judge, I would desaturate the leaves a little to focus the eye. Again a matter of opinion- you could argue that the agles bring you to the bird.
Nice head angle mirroring the leaf angle and the wing feathers mirror the leaf angle on the other side.
Just ideas- I am used to judges not liking my efforts
