I have 2 shots of mine that I want critiqued. Give me feedback on anything that I need to improve on. (These two pictures are completely unrelated. The first link is a sports photograph of a runner, and the second a photo for a "light and shadow" photography class assignment). Both were taken with a Nikon d3200, 18-55mm kit lens.
