Ok... I've been staring at this image for a while now...
To me the 'perspective' of the two female characters seems ok for the moment.
The thing that is bugging me is the incomplete environment lines. The way the ground curves around the females messes with my head
I dunno... perhaps the ground is meant to be uneven, but the way the females are placed on that slight angle suggests the frame is tilted to the left slighty and then the lines on the very left bring it back up again so to me it looks weird in that way.
But like you said it is incomplete.
