I think you may have misunderstood what Wes meant with his post about history. What he posted wasn't a history, it was a list of events that possibly impacted on his life.
Here's an example, it's one of my characters. You're basically writing a short, summary style biography of their life up to this point. Doesn't have to be anything incredibly complex or in depth, but at least an overview.
For the rest of it...
Facial features need to be reworked. Earth has been lost for a LONG time in this setting, there are no Cherokee, or Negros. Describe it, don't just list off stuff for people to look up. That part's also in the wrong spot, should be in the same part as the eyes.
You can just eliminate the ears section, if there's nothing out of the ordinary to be noted. That's mainly there since some species have non-human ears.
On the hair, when you say crew cut... Do you mean like
this, or more of the traditional enlisted
high and tight?
You need to describe the tattoos, if they're a major distinguishing feature. Where are they on his body? What are they tattoos of? I have a couple characters with tattoos, and it really helps to actually know what it is.
The measurements still need clarification in several spots. 220 what? lbs? And you should clarify inches or feet, non-Americans might not realize what the symbol stands for, where in or ft is clearer.
A couple things just pulled off of the character card up top. You might want to just make him Nepleslian, rather than saying human. Pure humans are a tiny chunk of the population of the setting, and Nepleslians are just slightly genetically weird humans. You also wouldn't be a full doctor, the way he's written. Doctors would be higher ranking, and probably only have been selected if they had prior education, or had already shown an aptitude as a medic. He could be a normal field medic at that rank, though, if that fits what you're going for. And last part from the card, go ahead and add the multiple measurements up there, too, with the previously mentioned edits. Should list both sets in every location either is listed.
Personality still needs some expansion. We're trying to get a feel for him as a person, here, and I just don't get much from things as they're written right now. The biggest thing, stop describing how others may find him, and describe HIM. Let us describe how we see him once he's in the RP, for now, you just describe him from an internal perspective. It also seems like the motivations section may have been cut off.
The family still needs to be filled in a bit more. At least an age, living or dead... the bare bones is enough. Most of the details can be filled in as part of the history, rather than a separate thing.
Under the skills, there are a couple of things. First, under fighting, a lot of the early part of it should be under a Physical skill, instead of fighting. Workouts, that kind of stuff.
Also, you have several skills that would fall under a single category, and aren't included in our skills system individually.
This is the full list of skills for SARP. Several would just fall into that Medical and science category, though you can feel free to differentiate them a bit within that category,
like I've done in one of my characters with her Maintenance and Repair skill. The big thing is just that you need to make sure you're including the information in the Nepleslian boilerplate skills, because everything listed there is a requirement for every soldier. You can paraphrase a bit, but everything is needed. It's also better to describe what he learned in sentence form, instead of lists. Again, this is all so a GM can get a feel for your character, a dry list of everything doesn't really mean much. Just try to avoid copypasting the description of training like you have, and put what he's capable of in your own words. Heck, maybe he's really good at some specific parts, but can't stand others. Everyone has their quirks.
I tweaked up the inventory a bit, but you still need to decide on (and edit to reflect) some of your options, like your issued swimwear, your rifle, and so on.
Good progress, but you still need some work. Keep goin', you're getting there.
