Critique Request on Concept art for a remake of Abadox Thread

First of all, I'm new. Hi! Hopefully I'm posting this in the right place.

Anyway, I'm mostly an artist and a fan of an NES game called Abadox, which I'd like to remake as a PS2-era survival horror game. I'm a big Silent Hill fan and I love the idea of a game where you're inside the body of a giant monster where it's pitch black aside from what your flashlight illuminates (plus maybe there's some bio-luminescence as well), and none of it is pretty.

This was an idea I originally had about 14 years ago, so some of what I'll be posting is old. But recently, I've revived the idea and I've decided to be more serious about it. I used to work for a small video game developing company so I know how to model and animate. Granted, I don't know programming or game design, so I may need help with that eventually (also not sure how to deal with the copyright issue, but I'll cross that bridge when I come to it), but for now I'm just playing with the general look of the monsters and such.

I would love some feedback. First I'll get some older drawings out of the way.

Here's a new one. I redesigned Parasitis and changed everything but the color scheme. For some reason, I kept imagining a giant sea slug, so I went with that. (I just didn't think a meatball with teeth was all that scary). The opening FMV would show the main character being swallowed by this thing:

Great art that last image looks positively friendly apart from the meteor.

Thanks, The splat.

I have done some more drawings since those first posts:

Some Level 1 Enemies:

Level 1 Boss, Deathface:

I figured Deathface should look a little less human-like, and I added a long tongue as a weapon. The original fired projectiles which I have a hard time accepting for some reason.

I'm currently working on re-coloring Bau (the dog). I think he looks good, but it was the first one I did and I ended up making the colors muted and "natural-looking", but since a lot of the ones I've done since have been more colorful, I feel that Bau should match.

EDIT (because I can't make two posts in a row, apparently?) - I decided to re-color Bau. I'm still happy with his general design, but looking back after having designed and colored a bunch of other monsters, the "realistic" muted colors I used on him no longer fit the aesthetic I'm going for, so I just re-scanned the original drawing and re-colored it:
