Ah that's good, thank you!For me, I think it's good if the description can be spread across multiple lines, paragraphs, one at a time.
You don't need to spend an entire paragraph telling people what a character looks like. Start off slowly, probably telling a bit about his/her height or basic attire in the first one. Then have the character interact with the environment or something like said character's hair or clothing, and sneak in some other descriptions while he/she's doing it.
That will not overwhelm your readers while giving you a chance to be descriptive.

Now he was a sturdy straw-haired man of thirty with a rather hard mouth and a supercilious manner. Two shining arrogant eyes had established dominance over his face and gave him the appearance of always leaning aggressively forward. Not even the effeminate swank of his riding clothes could hide the enormous power of that body — he seemed to fill those glistening boots until he strained the top lacing, and you could see a great pack of muscle shifting when his shoulder moved under his thin coat. It was a body capable of enormous leverage — a cruel body.
