The areas I've circled in red are incorrect - those tiles are actually used to connect multiple levelled cliffs (if you notice they do not match the dirt colouring on the bottom). The areas circled in green are an added line of cliffing that is also what I call incorrect - the way the cliff forms looks wrong as I see it.

Hope that helps - and I do like your way of detailing. Simple and not overdone. Much how I think it should be done.
