you did a very good job with the blending. the colors are very well chosen and blend well in the background and foreground. the outfit korra is wearing compliments her well and i can't wait for the comic.
well i have no idea what else to comment on so i'm just going to do this:
you need an idea?
OH! how about korra, like, went missing and she really just went to the underground part of republic city and mako and bolin and everyone are trying to find her but she's on all these crazy spirit adventures because she needs to connect with her spiritual side?
