So far, this is clear and the language is fine.   Will you plan to use some photos of models as examples of both good and poor composition?

The transition from rules of thumb (such as thirds) to actual photo shoots would be very helpful.

I have written one tutorial and agonized over it and revised a lot.  I wish you well in the writing and composition of the tutorial.  I will be greatly interested in your views and believe other will also.         Tom.
