Not sure how I feel about this set yet. It's going to be a tough one to get right, especially after the McDonald's prototypes!!
I'm not sure if you're staying away from it so you can keep the set's theme more flexible (ie Eva/Ironman), but a brighter red and a splash of green would go a long way towards making this look like Unit 02.
I don't think the colors you're using now remind me of unit 02 or asuka...to be fair, I haven't seen the Rebuild of Eva yet, and maybe you're not basing it off the original, in which case, why not?
At the least, the old NERV logo is worlds Better. I know HolyOOPS etc have done the old logo, but I still think it's the best one.
Anyways, yeah... gonna be a tough set to get right, but you've taken some really good steps. If it were me, I'd probably try adding in a little green and orange, brighten the red, see what happens? I mean, this is an SA set, which means it's going to be super glossy...a nice bright glossy Hellrot would go a long way towards both making a stunning set that stands out (the way Asuka is meant to)
This is a fantastic concept though... Asuka has been my wallpapers at work forever. The vibrancy of the red and green, plus her orange hair, is what brings me back to those wallpapers every single time. I can't help but feel it might do the same here.
