good placement of subject
BUT, bad angle of subject
i like the background, but the angle chosen here for the lifesaver is undoubtedly awkward
as to how to improve this, i guess there is no real choice, you have to keep the idea in mind and wait for a lifesaver at a better angle with similar background.. unless you are crazy enough to mess around with the lifesaver.. which is fine if there is freedom of movement and you do not spoil anything. otherwise..
