Render appearance doesn't match what I see in the viewport render

I would appreciate some guidance, I am reasonably new to blender and have been following a tutorial very diligently, upon pressing F12 however it isn't showing how I have been creating it to look. The shadows are all black and there are none of the darker shades on the path.

The Viewport Render (Viewport Shading - Rendered)

The Render Window

Is there any way to make what I am working on look exactly the same in the render window? I have been googling this issue for about 3 hours now but cannot figure it out.

This is in EEVEE, Ill also attach my shader I've used for the grass.

Thankyou all in advance,
