These are beautiful shots, Lloyd, especially the last one.
I'm not a bird photographer except by miraculous happenstance, so I'll focus on # 2 and #3. The flower is nice but the background is too busy, and there is some distracting glare on the foliage. If you aren't using a circular polarizing filter, you should be to remove that glare. There are a couple of blurred whitish areas at the far left which are particularly distracting; again, a CPL would help (as would cropping but that would cramp the reach and direction of the flower). I really like #3, the B/W, and would like to see a download of it. Is that possible?
Thank you SWFeral for your suggestions. I didn't have my CPL with me at the time. I was not actually intending on a flower picture; it just presented itself.
