What does the IMAGERY used in the first paragraph tell the reader about the captain?

I remember him as if it were yesterday, as he came plodding to the inn door, his sea-chest following behind him in a hand-barrow – a tall, strong, heavy, nut-brown man, his tarry pigtail falling over the shoulder of his soiled blue coat, his hands ragged and scarred, with black, broken nails, and the sabre cut across one cheek, a dirty, livid white. I remember him looking round the cover and whistling to himself as he did so, and then breaking out in that old sea-song that he sang so often afterwards.
