Ethereal

Decrease the transparency of the text a tiny bit, it's a little hard to read. =/

 

And that's gonna make it better? lol
IMO it looks way over blended, as if it was a thick mist or fog.
I like the middle of the chest plate, that caught my eye.
Opacity of text is good, just try toning to down an bit with the blending :b

 

I think that maybe adding a subtle glow to the Spartan he wouldn't be so blended in with the rest of the signature. Maybe make a glow on the visor and the right arm.

 

Still too blended imo

 

No, its much better, it feels more vibrant and alive, but the text is still hard to read
But that doesn't really matter, because it creates the mood and it flows nicely
that DARK spot in the corner messes with me though, maybe remove it

 

Right shoulder seems a little to contrasted in V3. I like V2 though, that one is the best so far.

 

Blending still hasn't changed and until it has I doubt it will get better. It's also too contrasted and sharp now imo.

 

Do you even know what blending is?
