It's still feeling a little "photoshoppy" so I was wondering if anyone could help me point out why

Exciting work, Paris! Nothing jumps out as needing to be changed, but here are a bunch of small "maybes" for potential adjustments to see if they help:
Could it be a matter of the lighting? Mark Hamill and Darth Vader look very close to the desired effect, but Carrie Fisher is a bit flatly lit (like a regular photo, rather than an "epic" portrait). On the right, too, the buildings are a bit flat (otherwise, the right side of the cover is darn-outstanding).
Likewise, maybe tighten up the color palette even a tiny bit further, to get the green out of Carrie Fisher's top?
Along with the overall outline glow, it seems like Sturzan enjoys adding little bursts of light; maybe some additional small pings would further enhance your effect?
For the background treeline, perhaps add a very slight gradient lightning the bottom?
It might be worth playing with the black hues under Selective Color to give the darkness a slight blue-purple tint?
Also, the title treatment is almost definitely contributing to the "photoshoppy" feeling you mentioned. I think you need to work your magic there -- either in losing the perspective, changing from plain white text, or adding some sort of interaction with the composition.
I hope something in there is helpful and look forward to seeing where you head with this one and the series as a whole
