My Issues

This doesn't seem very ubiquitous. Are you teaching a marketing class? If not why do you have "marketing objectives" being used a lot alongside "legal norms"?

This seems too highly tailored to a finished final project rather than a project by project basis.

Also "No important content is found within .25” of the document." isn't a composition doesn't scream composition to me. This should be outlined as a project requirement not within your grading specifically.

Additionally I rarely, if ever, had to adhere to "legal norms". If you are teaching a high-level (grad+) packaging design class this is almost a given and should be outlined in the project requirements.

Both the above should be lumped into 1 grading line like: Adheres to the project requirements.

In my opinion it sounds like you are grading your students/telling them to make you a final sellable product/project.

I had a professor in university try and enforce such "industry" standards to then try and use student work for their own gain (not implicating that you are). Personally anytime I saw this I got skittish and questioned the project I was assigned.

Review of Categories

Relevance

I don't agree with your use of this term. Relevance can mean a lot of things but it shouldn't be used as a grading metric. What I think you are looking for is a category that encompasses and grades on the Project Goals and a student's adherence to them.

Harmony

This is critique cop-out garbage in my opinion. This is what you spout out when you are called on to critique someone else's work.

"Oh I like the harmony of the greys with those red highlights" or something to that effect. No substance.

All these grading points should be removed and put under something like Cohesiveness or put under Composition.

Composition + hierarchy

These should be just Composition and hierarchy should be a point under it.

"The rule of thirds is taken into account." "No important content is found within .25” of the document."

These should be under the basic project requirements or in the class syllabus. The rule of thirds should also not be under there at all unless you are specifically grading a project where that is the focus.

Rhythm

This again should be under Composition or Cohesiveness

Originality + impact

These are "critique subjective" but sound okay. However I don't think impact should be in it though.

Summary

I think you have a decent basis but you are all over the board on your requirements and categories. You need to make a distinctive list that doesn't overlap or have items alone that should be grouped. You also need to have a lot of those points in the actual project requirements rather than in the final grading. This can be as simple as putting a line under Project Goals that says adheres to the project requirements.
