Life drawing classes aren't about making things real. They're a disciplinary teaching. People go to university and study for years to learn how to produce concept art, and life drawing is a key part of their curriculum.
I have no idea what life drawing classes are, but I do love concept art. http://us.blizzard.com/en-us/community/conceptart/
I would say that it looks good. That's good enough for me. (Plus, in your original remark, you used the word "obviously," making it come off as offensive. That bugs me because I just made an artwork, and most of the people I know said it looked cute (not good, necessarily, but pleasing in that it didn't try to be fantastic). The artists I know said it looked bad. That makes me sensitive to artists saying potentially offensive things about art, as it kind of hurts.)
Well get used to it, if you want to be an artist you've gotta let people rip you to shreds. It comes with the job.
It's the military gr(a/e)y outfit. True... But (for me, this doesn't apply to S I don't want to be an artist. All I wanted was "Nice job, that looks good" while I wait for those artistic people to make their own thing for it. (I suppose I forgot to mention that my artwork was a temporary splash for mah modpack)
Just like the Avian (Tonauac/Kronk) can be massive, so can the Apex be petite. Though I don't think she's very petite either, stereotypical corset waist notwithstanding. These are individual characters, not a model of an entire race.
Yeah, they would probably forget about the key. And the glitch were created, so I wouldn't think they would get a key either.
Love Nuru, glad my main non modded character is a floran! I like all of them except the apex (think it's female, thought it was male with just the head shot earlier). Then again, non human great apes creep me out badly so you'd be hard pressed to get me to like an apex character model/drawing. I wonder if Esther has laser cannons in that chair.
