This enormous painting continues to challenge me

It is 150cm x 240cm on primed canvas currently stapled to the wooden wall of my studio

The main debate with myself is about the horizon line. I am gradually settling to a decision to keep the horizon visible only on the left. On the right the orientation of the landscape becomes ambiguous.

Today I added a pink layer over the darker tones on the top right section and also some ochre areas. And then applied solvent and made some deep marks with a palette knife to reveal the dark blue underneath
