Camera I: Shot Size Evaluation

In my Shot Size Practice, I successfully kept my camera steady whilst filming a number of the shots, such as the Medium Long Shot. My camera kept focus of the moving figures in most of the shots, and I was able to capture the full essence of some of the shots, especially the Close Shot.
However, in some of the shots, my camera jolted and shook, and was occasionally blurry, due mostly to the rain, and the steadiness of my hand. I also poorly executed a Big Close Up, and instead filmed a Medium Close Shot.
To improve, I shall try to keep my hand steady when filming static and dynamic movements, whilst also I shall follow the figures movements and keep the camera on the same shot size in the shot, by not following with the camera anything else but the person I am meant to be filming.
