How would you physically describe a fictional character named Hotheaded (as in short-fused)?

Flush skin and face. Bulging veins in face and neck. Bed head hair and one eye is always raised a little higher than the other. Always appears to have a grimace even when at ease. Always has clenched fists and jaw as though grinding their teeth. They breathe in through their nose really loud and often exhales with a sort of malcontent sigh. And the last touch i can think of is tremors..like an unreasonable shakiness about them especially in the hands.

Hotheaded looked at me. I looked at him and took in his features. He was tall, very tall. I already felt as small as a munchkin. His eyes were a dark, but beautiful green, which searched my soul. Hotheaded's pale skin was as shiny as a ghost, matching his fire-coloured hair. His clothes hung over his body, making his long, thin limbs look short and baggy. It was a sight I'd never forget.

Is that okay?

He is stout, short but feirce, with a gaze that just says tick me off and you die. though true he was not always so testy he has grown to be very tempermental. Hothead, Sam Micheals(or wahtever) to be exact is just one of those people; the ones you want to stay on their good side for.

Um, I got what you meant the first time, so no need to repeat. You want to show someone hotheaded, but can't find the description to show it.

I'll do you one better. I get stuck on lots of ways to show many emotions, so I saved a page from someone who took the time to show all emotions - http://www.writing.com/main/view_item/item_id/1247...

It's all in the writing style. Tolkien had the best style for his people.
