Looks good! My first impression would be that the white suit markings would have a "light-up" feature to them (I've had TRON-LEGACY on my mind as of late).
What I like about the modeling of your characters is that you're sticking with more realistic human proportions than what seems to be norm elsewhere on DA, while also not getting into the so-called "uncanny valley" by becoming too photo-realistic on the human details. You've also put a lot of work into the environments that these characters inhabit, which increases the believability factor, rather than just adding a generic background (granted, in the majority of the other DA Poser-type arts, viewers are more interested in the hyper-sizted "goods on display" in the foreground, rather than whether they seamlessly fit into their environments).
Since you mentioned SPIRITS WITHIN...
Because of how that movie ended up being received, it was very interesting how Sony/Square-Enix pushed back from an attempt at hyper-realism and tried a middle ground with FINAL FANTASY VII: ADVENT CHILDREN, which in my opinion succeeded very well from a technical and artistic standpoint.
