@salami011, man I'm sorry it's taking me so long. I'm going to do my best to give you something actually worth your patience (same goes for all of you!)
Looks: So, just because I'm trying to actually do something… for his eyes. How would you describe them? Are they sharp, soft? How would you describe them in better detail? (For e.g., I have a set of siblings, and one of them has "Soft features, all except her rather sharp icy blue eyes." and the other has "Sharp features, but soft ocean blue-green eyes"). For his hair, I've got some idea, but more detail would definitely be lovely! Is it soft, and wavy? Or is it dry, due to the frequent dying? You have "Nick is naturally pale.", which has me wondering if he tans often? Just asking! (And I know this looks like a lot, but clearly I just over explain- ahah)
Mannerisms: These are great! Though I see you were struggling to explain one? What I'm getting is that either A.) he talks himself through a situation, trying to just think straight. Or B.) He just mumbles off in rambles, not really working through anything. Just a noise to distract him from their current situation. If neither, and you're still in need of help, just hmu or ask here!
Flaws: They look great! Though, I have one question, just because one of them fits me. For being indecisive, does he get stressed out when he has to make an on the spot decision? From personal experience, I get stressed out when someone is getting frustrated at my indecisiveness. Eheh-
Fears: That's a good thing to add! Though one thing I'd add, is more in depth about how he would react if he were in such a situation. Does he freeze up? Does he start breathing quicker? And maybe how well he handles/hides his fear.
Andddd I promise to come back! It's taken me way too long to do this- eheh… I'll finish it, I promise you!
Favorites: It looks like you have it for one of them, but just thought I'd say this. For his favorites, give reasons why they're his favorites. Not really with a ton of detail, but just a little bit of reason why he would like what he does.
Julia: So, you seem to have her mentioned yet when looking at it, she doesn't seem to exist? Or maybe she's locked, so I just can't see her. But I was just going to ask, if you think she should be put under friends, or somewhere else. Just so you know the two have a relationship of some kind.
Others: For a few other notes, which you may have written down somewhere, but I'd take the time to find out a couple things. Such as his Hogwarts house (even if you aren't a Harry Potter fan, it's just a fun thing to know.), and/or his Zodiac sign.
That's all I have for you! I hope I was able to help!
