Like I said, a bit more patience and with a bit of tricks and rotations, you can get a pretty sick fight scene. Rather than keeping the characters in one big block, you can separate them at the knees, elbows, hands, etc. and then rotate them to new cool positions. You can rotate things with the right click when on the selection tool. Also, next season, or wherever you are going with this, why don't you make the panels a bit bigger, maybe 4x? I know it seems like a lot, but it leaves room for detail and is easier on the eyes.
