Responses here seem to come for really good pictures and for really bad pictures. A lack of responses isn't always a bad thing. Its just that the pictures don't stand out as much.
They are nice pictures.
#1 - there are some hotspots in the bark, where its blown out. This often happens when shooting on very sunny days, with shade. Nice colour saturation and good composition. I like the lines in the pictures
#2 - Nice sharpness and colours in the picture, but I don't like the composition. There is lots of empty space on top of the duck and I would prefer seeing more of the body or less of the body and closer on the head. Practice at filling your frame with your subject, as you did with the tree.
