Think I fixed the leg-torso problem, and I'm currently reworking the pose a bit to look a bit more natural.

Much better! Personally, I liked the older pose but perhaps his left hand could be behind his head? Might make him look a bit more... innocent/cute.

I think the sprite looks a little manly for a girl:


Some thoughts on the idle animation:


Some thoughts on the gun animation:

Personally, I like the idea of a beefy girl character. I think I feel that some of the changes you made (super slim, breast jiggle) are kind of overkill and make her feel like any other female character now days.

Good looking sprite, I like the hair animation Here's an idea on adding recoil and fluidity to the shooting anim:

I feel like this is a big improvement to the gun animation as well. I might take a crack at the recoil animation in a short while once I have time to spare, but great work so far! I really like it. 

I've been watching this thread for a while and I wanted to just wanted to offer a little food for thought. At the current time, with the tufts of grass getting darker as if they're receding into the ground seems rather strange to me and feels really unnatural. Normally the grass would be the darker shade and the large tufts that raise above the rest of the grass would be lighter. So with that in mind I went and swapped the light and dark greens and came up with this very messy edit:

Now this isn't any where near perfect but I feel that it does illustrate my point as I feel that the grass here has a bit more natural looking depth to it. Could be wrong though! 

Rubble? As in, the remains of long-destroyed or eroded away structures?
Right now, all those light beige dots/rocks just looks like a different type of natural earth/ground, to me.

Why that prominent vignette? Makes me feel like I'm viewing the world through a telescope or something.
I assume you're just trying to make the world look less spot-colored and want to introduce some gradation for enhanced impact/depth. Which I agree with, but I think your execution is lacking.
See a Hyper Light Drifter example of gradiently shaded low-res pixels.

Rubble as in what you've stated. The vignette is something I implemented quite a while ago to give a bit of cinematic look to the game and to supply a bit more depth and visual interest. Do you have any suggestions on other ways that I could go about this?
Here's an edit on the tiles:

Although now I feel that they don't really look weathered enough or broken up but I do like this much more than the others I made.

Hello! 

Since I feel like I can't properly comment on the BG or some of the rocky outcroppings that the character is standing on until I see them in a slightly more finished state, I'd like to talk about your dirt/main ground tiles. Even with how things are rather unfinished (at least I think they are) there seems to be a real clash of style between the rocks and the dirt, specifically with the pattern you have in the dirt. The rocks have very blocky and large surfaces and look smooth where as you have this strange grid like pattern in the dirt that comes off a bit more like brown circuitry to me. I unfortunately don't really have the mental capacity to whip up a few edits (I spent the day helping a friend move), I can at least suggest trying for a pattern that isn't so broken up but rather more whole like your rocks. A lot of times that I've made ground tiles I've found that sometimes a little less detail goes a looooong way. 
Again, I apologize if this didn't make a whole lot of sense, if you have any questions I'll be more than glad to be more concise
