This is a very striking image. The bird really pops from that uniform green background, especially with that magnificent crest on full display. The perch, as noted earlier, is a bit strong, but that little bird still overpowers it in my opinion. You might want to consider removing one of the catch lights.
Hi Willem, I love these little characters and you have captured him wonderfully. I wish I could get one in such nice circumstances as all I have so far are obscured by branches!
