Also I'm not sure what icon to make for dampeners... a red X over a thruster icon when they're off ? Or a thruster icon with a spring coming out of the nozzle (literal dampener =) ) when on ? Other ideas ?

Do you already have some sort of a mockup for that? Might help with feedback.
Having all lifesupport bars on one side and other stuff like volume, speed and dampeners on the other side would be coherent, but might also clutter th UI too much.
A centered bar on the bottom could interfer with the actionbars.
Regarding the actionbars, do you have any plans on adding these? Would be practical not having to switch between the original HUD and yours, but again, this could add too much on your UI.
But this might be something to try out with some quick and dirty mockups and then look how it feels.
Good UI design usually is quite hard task I have a lot of respect for and I like your approach a lot more than the original SE UI. I really hope that Keen get inspirated by your work ;)

I do actually, this is what I currently have:

The broadcast icon is now a mesh (it was just a texture) not sure if I should leave it like that.
I don't really like the dampeners icon though, still looking for suggestions on that one.

I'm not sure if I can get the actionbar stuff, I'll investigate.
However, a problem would be that it would collide with the existing one since I can't tell if the game HUD is on or off.

EDIT:
I can read the taskbar, but the problem would be that I can't display the icons nor text xD

Could you also add speed, gravity and pressurised envinronment ?

@Shadow
As I already said in the comments, no.
Text can only be done with LCDs and those can only have opaque backgrounds, and it looks weird.
Also there's no way that I know to get the pressurized environment arround the player.



A more updated screenshot: http://images.akamai.steamusercontent.com/ugc/44250978848383729/F31EDE04ACD69CBFA67626B1C1B711675FBD0686/

If you understand what every element is then it's good, if you don't, let me know which xD

The warning icon on top blinks along with the representative low bar(s) btw :P

That looks really cool btw!

well for something in the bottom center of the screen you could have a compass that points towards spawn, and the radio signals could appear like in Fallout 3/NV or skyrim, and then if the signal is coming from above you or below you it shows a small arrow pointing up or down

i recommend you to do a development mod where you upload the testing of youre mod and let the people tell you what you could improve

But I think it might deviate from the simplicity with too many shades... xD

is the hud, transparent blocks or something? I think the simpler version looks better. although the underlay for the bars is a good addition.

Simplistic version of the updated:

Can you guys tell what's the icon next to the broadcast one ? If you do then it's perfect.

Not sure if the inventory bar is understandable what it is or what it means XD
Also, with or without gray background on the broadcast and the other one ?

the thired screenshot looked pretty good... and the symbol for the dampers is good... but you should add an info in your description...

and the gray background is perfect, so you can tell how full of O2/Health/Energy/Volume you are...

Add what info in the description ? O.o

And I'm talking about the background for the broadcast/dampener icons, not the bars.
