Sherlock Holmes chara design exercise (schoolwork)

A work for my charadesign class : the theme was Sherlock Holmes .For this project, we had to redesign three characters : Sherlock Holmes, Mrs Watson and Mycroft Holmes. Two conditions : they had to be of diferent ages and be living in the Victorian era.
I was asked for each characters to produce a turn, a color lineup and a full page of poses of this design we created for them. I also had to draw environments with one or multiple characters interacting in it, and a keyshot to show how it could look in a 3D setting.
