Yup just more practice, various styles! The girl is meant to be Carolyn Stoddard Collins (I'm sure I messed up her hair :p) and the man with the flashlight (as well as the super deformed guy in the center of the page) is Willie Loomis, both from Dark Shadows 'cause I love that show. No surprise that when practicing humans I pick DS characters as subjects. XD

The little kid and the random person at the top are just that, random. I sorta love the toony kid the most, not sure why. Such a fun style that one is!
