I'd say this is a very asymmetrical artwork with asymmetrical items! The proportion of the items are very inconsistent.
Explanation:
There is repetition of items, such as the boats, but they are not symmetrical to one another in the composition of this artwork. The cliffs only appear on one side of the artwork (right). it is a very asymmetrical artwork.
Asymmetrical- a design that has unequal visual weight on either side
