Minor artwork improvements

I've updated this game with just a few minor graphical improvements. 

The latest artwork in my most recent games has improved significantly since I started, so I've redrawn a few of the worst images in this game to make them better.

There's a lot more that I could do, but redrawing all the art will take time, & I'm sure people would prefer me spending that time on adding new content to LEWD MOD 2 instead. 

So I'm hoping people will enjoy seeing the full journey as the art goes from worst to best!
