Well, since I actually have a computer for an hour or so, I'll scan through really quickly and give you at least a barebones rundown on what all needs to be fixed.
First off, headers and other fields that stand on their own, like the character card, should always be capitalized. Medic, not medic, each of the skills needs to be capitalized, and so on.
Height and weight need to include both metric and imperial measurements. We have members all over the place, so this is just a convenience thing so different groups don't have to try and track different measurement systems.
Build needs a lot more detail. Average for who? Average in what sense? You're being far too general. The goal of the physical characteristics section is that we could hand it to an artist, and they could come remarkably close to what you picture in your head.
Distinguishing characteristics should be changed. This is basically... Well, if we were trying to pick Jace out of a lineup, what physical features would stand out? What would make us remember him? Tattoos, piercings, does he wear his hair in a weird way? Get inventive, this is one of the categories where you're actually encouraged to point out the more outlandish stuff about the character.
Personality needs a lot more, I generally ask for at least 3-4 complete sentences. What drives him, how does he think?
This is a great guide for helping you flesh out a character's personality, just requires you to sign into a DA account.
I'd also like to see more on his likes and dislikes. These lists can be HUGE, and are great for adding more little details to help keep a character from feeling bland. You can very nearly literally include anything here.
I'd also recommend some less nebulous goals. Think short term, not just long term. Where does he want to be in five years? What does he want to be doing? You don't have to get specific, but goals should be something that's more obtainable.
History needs a lot more fleshing out and detail. He's been around for 18 years, I'm sure more has happened to him than that. No friends? Didn't do anything in school? This is his life, fill it in.
I'd also think twice about the hospital stuff. He wouldn't have been allowed to assist in a hospital, especially in this future level. Even the most basic nurses require schooling to work, and there is more than enough automation to help in most cases medically. There would be no reason for them to risk letting someone with no training or background in medical stuff help out.
Skills, same general idea. Flesh them out, at least 2-3 full sentences where you can. Explain what he can do. Under medical, does he just know first aid, or first responder stuff? Does he know how to do surgery? Tell us what he actually knows, not just the name of the skill. Communication and Fighting are both included in the Common skills, as well, so you don't need to list those unless you're adding something specific to the training. You should also link to the common skills if you're just inserting that, not just say he has them and leave us to guess what they are.
You need the standard inventory listing as well, either on the page itself, or a link to the standard equipment list.
This is the inventory page, I leave which system you want to use up to you. Either way, you should list the extra inventory items in the same manner.
The AI needs more detail, both for the AI itself, and for the body it uses. What is the body capable of, what is the AI capable of, and so on. Honestly, I'd... skip out on that unless you absolutely need it for the character. We don't recommend trying to make technology for the setting for at least your first couple of months, just so you can get the hang of things, and that's basically what you'd be required to do for this.
Just in general, as has already been said, you need to work on the spelling and grammar for the page as a whole. I usually recommend putting the article through M$ Word or OpenOffice Writer, just for the sake of saving you time. The entire article also needs to be written from an outside, factual perspective, just like an actual Wikipedia article. Phrases like "and that's where we are now" and "like I said" don't belong in this. Think of this as god's character sheet, not a discussion.
Annnnnd... that turned out a lot bigger than intended. Don't sweat it too much, mot of it is minor stuff. Just work it out bit by bit and you'll get it taken care of.
This character submission is
