Any guidance or techniques to achieve more realistic lighting in each season?

[TyroneClark]

My current challenge lies in creating realistic lighting for my project. I want to avoid the route looking excessively bright as if it's being fried by the sun, or on the other extreme, having the sun barely shining. My objective is to make the route visually appealing and authentic for all seasons, including winter, spring, summer, and fall. I would greatly appreciate any guidance or techniques to achieve more realistic lighting in each season. Thank you for your help!

The seasons should change automatically as the real date progresses through the year. Look in edit environment to set the brightness levels.
