Crap. I was hoping this wouldn't be very noticeable, and it's a very valid criticism.
Here's one of my dirty little secrets. . . . The hands on hips is me cheating. I did several turnarounds of Savunn (civilian clothes, Fusion, and Fusion powered-up). Everyone of the hands-on-hips pics is the result of me cutting and pasting from my turnarounds (and resizing a bit). The pic with both hands on hips is just cutting, pasting, and rotating her left arm from said turnaround and making it her right arm too. I periodically do cheats like this to speed up page production. If you've seen my Great Scott saga, you might notice that I recycle certain faces. A lot of times I'll redraw the mouth or eyes to change the expression, but the basic outline linework stays the same. I try to keep a steady output of material, and with a family and full-time job (and hour-long commute), I don't have as much time to spend on doing these comics as I'd like, so I periodically employ cheats like this to maintain a steady pace of page output. Good news is I don't think I use this pose any more in the comic (well, this issue at least).
