1 I was tinkering with RPG Maker last weekend.  (It's an application for making old-school role-playing games, like the early Final Fantasy games.)  One of first things I checked was whether you could give a character red half-rim glasses.

Not only can you give character portraits red half-rim glasses, but the animated sprites automatically get teeny-tiny red half-rim glasses too.

2 Um, why would you mount a semi-auto handgun to a bipod like that? The bipod can't be folded back up anymore with it like that, and the handgun is practically inaccessible with the rifle there.

3 It's an alternate firing position, to be used when she slips into super-deformed mode and can't handle the rifle anymore, of course.  

4 I don't think there is any way in which this post could be improved.
Excellent work, Steven!
