Jonathan, The teasel makes an interesting perch. Very sharp details and I like the image design. I might tone down a few spots. I agree a slight head turn would be good. I do like seeing the foot on top of the spikes and the tail in the clear. Nicely presented.:)
Terrific perch and a nice BG. More eye contact would have been nice. I would consider a crop that puts the bird higher in the frame and allows us to see more of the stem.
