Taylor's Sketchbook of Patterns and Progress.

I think what the last piece is missing is a sense of harmony i think it as to do with how different every character are i don't have anything on top of my head to suggest but i want to bring attention to this anways. Also your composition doesn't create a loop around the whole thing it make the eye escape to the right of the composition due in part to where all the character are looking at.
