This is indeed a striking image. You have done an excellent job of making that eye piercing - a very effective use of selective desaturation (and a bit of selective saturation too). It combines to give a high-impact impression. I love the funky 'hairstyle' of the featehers, and think you have done a good job on the texture and sharpening here - it would have been easy to over do it, but you haven't. I don't think that the overall image gets much from the negative space to the left and right of the bird; a better crop in my opinion would have been closer horizontally, and with a bit more vertical to include the top of those interesting feathers.
