I think Axel hit the important tech. points. I do agree about the crop up. Head angle very close, but yes, I think a couple degrees more towards us would be great.
Lovely colors, I particularly like the lighter green on back.
My friend from Texas has some great images of painted buntings. Have not seen this behavior. You did an excellent job with exposure and color control. I heard they like bird calls.
Thanks for sharing this nice photo...
