I think I've got the characters for the group project comic to a pretty good place, so I wanted to post an update showing where things are at. 

I wanted to try to achieve a look for Cassandra of the lazy "hot girl" in class who never really does much work since she can charm most guys into doing all her work for her.  She barely even shows up for their chemistry class anymore, and rumors are she blew the T/A to give her a perfect attendance record. But those might just be rumors. With 2 nerds as her partners for their end of semester group project, she figures she's getting an easy A.  

I made some subtle adjustments to my standard female model with this comic, wider hips, narrower shoulders, and slight tweaks to the breast and ribcage shapes.  

Caleb and Alan share a dorm room in addition to the chemistry class, and while they aren't bad looking individually, they tend to watch anime and hentai more than talk to real girls, and could never hope to pull a girl like Cassandra anyway.  In fact, watching hentai is how they came up with the idea for their aphrodisiacal cream in the first place.  Caleb is the smarter one who made the chemistry breakthrough that makes the cream work, but both are equally excited for the chance to try it out on their hot classmate.

My goal was to strike a balance with the two male characters of making them look nerdy enough that Cassandra is totally out of their league without them being objectively unattractive.  

I'm still working out the story plot points as I write this, so everything is still subject to change, but let me know any feedback.
