[WIP] Serena and Chloe (Pixiv Fanbox)

The next request is actually a Serena comic. As a refresher I decided to just draw a simple Serena illustration since it's been a while since I last drew her. Chloe is in there too.

So which one looks better? The bigger one (left) or the one that focuses more on Serena's boobs with Chloe's reaction.
