Notice the well defined shadows in your images (as opposed to soft shadows). To get soft shadows, move your light source closer to the subject and/or place diffusion material (tracing paper or anything other white, translucent material) between the light source and the subject.
Also check your white balance; it doesn't seem to be the same in all of your photos. It looks rather orange in the last photo and looks best to me in your second photo.
