I decided to work on this further at home. Still not sure it's working, but I'm a bit happier with it than I was the other night. Simplified the foreground tree as per Tom's suggestion (probably could do more), and got rid of an extraneous bush that was awkwardly placed. I'm still not sure if the sky is working - I definitely struggled with the fact that the view faced west. I'm not sure how to deal with the bright glare of the low sun - next time I'll try to pick a view opposite the sun!
