Suggestions for rubric refining: Merge the concept & product rubric.
Product Rubric:
Change Organization to Audience awareness, & combine with Expression
Keep Focus as is.

Concept Rubric:
Keep the top two areas
(adjust the adaption area/this needs to be explicitly taught during the unit - suggestion: top area called historical influences, second area called Modern influences)
Delete the the two bottom areas (as influence on environment is not really focused on in this unit)
