I am having some troubles describing this male character. I would like a bit of assistance please.?

Thing is, MOST authors leave the physical look to the imagination, they don't do a laundry list of what color the hair/eyes are, the length of the eyelashes, the size of the big toe or anything else UNLESS it applies in some way to the story itself. You don't need to do all that side work, your writing/plot should be doing the showing, not you doing the physical 'telling'.

If you are writing in 3rd person, he is not describing himself. You are describing him.

"His black, shoulder-length hair ..." is all you need. If he, like Samson, lost his power when his hair was cut, you can say it straight out, like the Bible story did, or you show him confiding his secret to his lover, his lover offering the secret to his enemy, her shaving off his hair while he is drunk and then the enemy entering the room.

Oh, I have an almost perfect name for this person, only unfortunately it's perfect only for someone who's 5.8 tall. Your character is 5.9, so OBVIOUSLY the name just won't do at all.

I'm making allowances for your obvious extreme youth, but seriously, why would it matter that he can't tell other people about his appearance?

No character is going to stand around saying 'My hair is dark and wavy and rather thick'.

You get ANOTHER character to notice him, and tell other people about him.

And don't TELL us that he's kind but won't take any crap. SHOW him to us in a situation where we can SEE he's kind but won't take crap. That's what writing is all about. Let us see him; don't blab on about his skin colour and the length of his hair.

Put a feather in his hair and a tommy hatchet in his hand and the kid would look like a young Crazy Horse at the Little Big Horn... if Crazy Horse had been at the Little Big Horn!

Seems to me you've described him.
