Just my opinions.
#1: Great photo. Everything works here I think. Background color tone follows the subject and then down to the stick (in hue). The square cropping works with the stick being symmetrical and the head being at 1/3rd in from left, plus good overall balance left-right and top-bottom. The "death grip" on a dead stick tells a story. Color of head has enough contrast to make it the focal point of the image. The DOF was good with focus fading away over the "body stripes" and the head totally in focus. Overall lighting is pretty good, some cutoff in the legs and the stick may be a little contrasty - not much staturation or washout.
#2: Don't like the DOF here - back of head (where legs attach) is slightly out of focus and that distracts me. Colors are stunning though.
