Rough idea!

After hours and hours of colouring the characters on illustrator I finally have a rough idea of the size, feel and look of each character! I like how they all size up to each other and I think they all look the same sort of style of cartoon which I'm pleased with! And I especially like the drama teacher with the skull and the headmaster! The colours aren't finalized and I haven't added any kind of shadow or real detail to them, but this is what i came up with! Again feel free to leave a comment on how I could improve them!
