Re: Chairs and a calm lake c&c
Look for information on values & aerial perspective in paintings..
You could soften the background hills with lighter values for distance
reshape / soften the mid ground trees & angular shore lines - maybe more of a blued gray green mix
Stronger colors can be used in foreground.. seems washed out or a water color look..
This is a nice composition & scene, take your time & don't rush to call it done..
Taking a break & studying on it is a good way to learn and improve..
