My First Landscape

I’ve never tried a landscape before, so I would like some advice, and any is welcome:

Your textures have really different style. You should somehow unite them.

also, the grass shouldn’t go all the way to that water, and if that is a lighthouse in the background (not sure about that, is it?) then you probably want to add some rocks to the shore. it is more of a rocky cost type setting?
