What a difference a little light change makes...

"On a Clear Day" 36x48" oil on deep canvas - painted in 2022 and hung in my livingroom, but still actually unfinished.
Three photos of it taken minutes apart in different light positions outside in the late afternoon. The fourth photo is how it looks under my studio lights.
Note to self: check how the painting looks where it is actually going to hang in my living room and under various light conditions that exist there. 
Self critique:  The light direction in the painting is unclear or diffuse. Time of day? Sun direction? Shadows? 
Willi critique: Where are the animals? Cows, deer, birds, etc. "but it's fine as it is too." (i.e., don't mess it up!)
