Felt like this was the right place to post works from PMG that aren't relevant to PB2, so I'm just going to share a bit of my work from the program here. Anyone else can add in their creations if they want and feedback/comments would be nice too. I made them links instead of embedded pictures because the width limit is 1200; some of these pictures exceed that.
