Very well, you asked for it.

Through your emphasis on Durandal's height, you imply he feels inadequate, shy, or lacks confidence. This seems like a mismatch, as Durandal in the games is purpose-driven, proactive, and self-promoting. Physically, I also see him as bald, but I don't have a justification for that beyond him being portrayed that way in the Durandal chapter screen.
If Tycho were to take a humanoid form, the white hair seems appropriate, as does his helmet. Less so for the overcoat. Unless I'm forgetting something, we don't see human characters in Marathon wearing coats or other loose outerwear. The trench coat just doesn't say "24th century" the way, say, BoB's jumpsuit does.
Leela is one of the more feminine characters you have. Still, I don't know how to put this delicately, but she and Cortana's avatars have breasts that don't look much like human female breasts. They're too square, like pectoral muscles.
Here's a non-sexual yet NSFW link showcasing the natural variety in shape and size.
Thoth is great. He looks simultaneously alien and intelligent. The "Thothandal" avatar is like 90% Durandal, but whatever, that's a tough one.
The Security Officer, "Vincent Callahan," wears armor that's pretty authentic, but I imagine his body should have more definition:
It's funny, but you've always been the colony's trouble shooter. You're bigger and stronger, and a better shot. In games, you always scored the most points and looked the hero. (

Again, the uniform is form fitting, and he canonically has a hero body type, so in my opinion we should see some of the musculature of his arms and legs. A squarer jaw would also look good.
Enzo Lynwood: Guess I won't comment since I don't know who that is.
S'pht Clans: Looks good. I like the ornamentation around the wrists a lot, though I suppose in a perfect world it'd look different for each clan. The shoulder pads are a creative way of distinguishing the clans.
Charlie and Lysander: I'll just say their faces look as feminine as Leela's, and again the clothing is awfully modern-day.
Marcus Jones: He looks like his dog died in every image.
Hathor: On the avatar version, the breasts curve better, but note the trunk-like torso with no taper at the waist like you'd expect for someone with 6-pack abs.
Yrro and Pthia: I see the Jjaro as too god-like to look this human. Like, they'd just be a blinding blue light the size of a planet or something. I guess that would make it hard for them to emote, though.

Space Between: The moodiness is overpowering. For what it's worth, Robert Blake looks nothing like The Man in the Online Asbestos Suit.
Never Too Tired to Kill: The face is lacking here. The mouth and nose don't line up, and the eyes are a bit crosseyed. His expression is one of fear as much as it is rage. Also, the torso seems curiously long, and perhaps unnaturally twisted a bit.
Mixed Metaphor: When "Vince" opens with "So, uh, these dreams I've been havin'," why does Durandal look like he's been hurt? There's nothing to react to yet! It's like his default expression is one of sadness, and I do not understand this. I doubt this scene takes place in the Melancholia stage of rampancy... this is what I'm getting at with the unnecessary brooding, angsty moodiness. On another note, I think Vince's nose is off the centerline.
Bernhard Strauss: Now here's a character with focus, that looks like he doesn't tolerate weakness or incompetence. Not precisely the attitude I imagined for him, but good to see represented in the mix. Note the not-futuristic business suit.
Overstepped Your Bounds: Tycho's face is like "ha ha, noogie time!" and Durandal is like "Oh God, I'm coughing up blood." I guess it works from the perspective of Tycho being a psychopath.
Bungie Day 2016: Oni's not my strong suit, but Konoko has always cut a trim figure, whether
in game,
in cutscenes, or
in reimaginings. The armor doesn't add much bulk.
Enforcer: Hmm. I liked the floor-length robe for whatever reason. When you narrow the one pair of eyes, it changes to look like a pair of human-like eyes that draw your attention, with some extra eyes tacked on. I liked how the original art looked like a fully alien face, with eyes in an unrecognizable alien configuration.
That's all from the first post, so I'll break it off here.
