The bird placed at this position in the frame while facing that direction adds visual tension to the image and makes me want to turn to see what's off to the left. Good use of colors and textures.
oh I love this one! on the roof in front of my window there is a pair of seagulls, with their nest and eggs (I'm waiting to see the newborn...) and I tried to do a picture like this, but the result was very poor, the roof is too far for my camera lenses and pixels :) I'm telling you this to explain my strong emotive response to this picture which makes me liking it very very much! on the technical side, I'm not an expert, but I think the colors are great, focus and definition are fine, the size of the bird compared to the whole picture is absolutely perfect, for me. 10! and good luck ;)
