Thanks for this topic! I feel the same about centered compositions, I respond very positively to them. Centered does not mean that everything has to be symmetrical, there can be variation and movement in a centered composition, in the way the secondary elements are arranged.
I like your mountain, it sits tall and commanding in the center of the format and this is a great composition choice for this painting.
there are many fine examples in art history of this type of artwork.
Could you name a few of the painters you are thinking about? I would be very interested ... actually I have thought about opening a thread asking about centered compositions within art history specifically, because I also am questioning the validity of the rule that the focus of a painting must not be in the center.
The one painter I know and greatly admire for his calm, centered compositions is Caspar David Friedrich
is a second example.
