Your last one is a definite improvement.
I really like the rusty pallette you've got (although it does need optimising),
it kinda reminds me of old skool 3d games like doom, and azraels tear.
It's quite hard to critique this, as some parts look awesome (colours, lighting in general, forehead, around the eye area),
while other parts are still a bit weak (the actual eyes themselves, the cheekbones, lower face, nose and neck).
But yeah I really like this, keep at it.   

This is looking awesome, can't wait to see it finished. I'd take the lack of comments as a compliment.

Critique-wise, her right forearm is looking a little odd in my opinion. I think if it curved from the elbow to the wrist in one smooth arc it'd work,
but at the moment it starts a little too far down from the elbow. Also her right hand looks somewhat disjointed, but I'm guessing that you just haven't
got round to working on that yet. I'm still a little unsure about the red fur, but that's just a personal preference. I feel that just having the lips,
and the blood bright red would be more hard-hitting.

Thanks Junkboy I like alot of what you've done with the face, he definetly looks more old master.
Drunken fist would be awesome, if a little tough to animate.
I've started drawing up different poses, and facial expressions for animating

This is the expression he'd use if he was to say something like
"I aint got time to bleed" or
"I'm gonna take you to the bank... the blood bank"

(I changed his eyebrows to fit in more with the old master archetype)

Just some quick consumer advice. I've been pixelling this in Graphics Gale freebie addition.
Is it worth paying for the full version, so I can export animations?
Or should I just download a different program for animating?

Cheers, I hope I aint breaking some forum rule with this kinda thing

Thanks for the edit Phil, it's definetly a more natural and relaxed position.
I feel that I'm leaning more towards a fighting stance though now I've been messing around the arms a bit more.
Here's a couple of quick sketchy edits I did on the arms.
I definetly prefer the big arms and hands as apposed to those of my original pencil sketch.



For the 4th one I was going for a kinda praying mantis style, I dunno if it works or not.
Tell me if i'm heading in the right direction with these. They were pretty quick to knock up, and I really wanna nail the idle stance of this guy

[EDIT]
That's cool Lostspringtidus, I always assumed platform characters were completely side-on. I guess you rarely see them stationary anyhoo

This looks awesome AlienQuark. I love the design of him.
The animation's looking good too, I feel the legs could use some subtle movement. Possibly just a simple up/down bob bending at the knees.
The animation loop is pretty obvious, but it still looks quite natural, given the restrictions.
With the back arm, I feel it looks pretty awkward compared to the other two. I'd add a slight bend in the elbow and wrist like the one in front.
