Excellent natural light image, with nice display of iridescence. Nicely scaled perch, with interesting detail.
In a perfect world, a bit more DOF would be nice. Obviously you didn't have any room on the shutter speed side of the equation, so might have been interesting to push up the ISO a bit, if you had time, to gain a bit more DOF.
Very nice as is. Oh, maybe a sliver more room on the right, because of the long bill.
