Right side up or upside down

I'm working on a new abstract aerial landscape painting but can't decide on orientation. Still some more layers to go -- as I paint I shift the orientation periodically. It will probably be obvious later as to how it looks better...What do you think?

Right side up:

Or, upside down:
