brains out!

As an anime fan I like the picture, and am curious as to the setting and story.  One of my ideas is that the men are caught up in virtual reality of beautiful women and are "losing their minds" by getting too into it and not caring about reality.  I have a few other theories, but overall, the picture seems to objectifying women and men.  The Women seem to be sexy, and beautiful, but quiet and reserved and out of the way when not needed.  The men are dark and sinister; maybe even evil.  The drawing style for the men seems good, but something about how the bright side of the picture is drawn seems a bit off.  I don't really know what it is.  maybe it was just drawn quickly and the mistakes show more without all the shadows.  The woman with purple hair has a kinda awkward looking dip in one side of her waist. I guess its because of the way she is sitting but it looks kinda weird imo.
Maybe the light side looks kinda weird because the style is similar to the dark side, but with bright colors.  or maybe I am just a bit too used to anime, or maybe the picture just needs to be finished.  I'm not sure why I'm assuming the picture is unfinished or drawn quickly.  maybe because the center girl's face looks kinda shiny but she doesn't have that same texture on the rest of her body.  and the other girls don't have much texture at all.

Honestly I wasn't going to write this much because I don't have any formal drawing experience, or much experience at all.  You were asking for critique and sorry if this doesn't help much.  I like the picture though and am curious as to what it is about.
