I also forgot to post refs for my characters... so sorry!!! =-=
Zoe is on the shorter side, and slightly pear shaped. Louisa and Gareth are both taller and kind of lanky. You don't have to include Sam, b/c I don't like how I drew his face, so that isn't how he's going to look. :T
Also yeah haha Louisa is totally wearing a ghostbusters shirt.
