One morning at Fort de Soto: We followed this guy as he walked along the shore. I had stupidly left my Canon back home and friend, Judy Malloch was gracious enough to lend me one of her Nikons and a 300mm f 2.8 (nice!) lens.ISO 400, f/4.8, 1/2500.
The comp is rather tight at the tail, and the head is ever so slightly angled away. You did manage a great low angle, and the walking motion is nice :-)
