How does Daniel's dad look?

From the text:

My father is looking older by the minute.

With his long legs crossed at the knees and his large rude eyes magnified by his glasses. Like Susan’s eyes. And his skinniness, and the same face I have with the big lips and big teeth, and round bulb Russian nose. And the sleeves of his blue work shirt rolled up to the elbows—to just below the elbows. I remember his thin arms, with then jet-black hair, and the sinews moving under the skin. The hair grew right down over the backs of his hands to his knuckles. He was skinnier than I am. His hair was like wire.
