1. This is an interesting shot. At first I didn't think it was anything special, however after breaking it down I actually kind of enjoy it. You tilted the photo, to give (hopefully) intentional motion as to the direction the pig is spinning. The biggest downfall of the image is that there is little subject-background separation. They are very similar in color, and sometimes you can get away with it if the background is heavily blurred or significantly darker / lighter however none of that is the case here. The background is blurred, however so are the edges of the pig, which again quite literally blurs the line between subject and background. Not knowing what type of photography you are going after - as a commercial photographer, I would have rather the entire pig be in focus with the background out of focus.
2. This is just snapshotty to me. Seems like there was little intent in this photo other than "here's a lizard!". Nothing wrong with it, just nothing I would post up for C&C.
For all I know the first image was just a random snapshot, however whether you realized it at the time or not there is intent in the photo. Recognizing that and growing from there is how you advance as a photographer ^_^
