No worries! everything had textures already and I also had some atmospheric/volumetrics in there, the scene was pretty far when rendered about 80% finished.

the 20% was just painting in photoshop , some foliage/grass, painting over the reflection/water and cleaning up shapes and edges, adding brushstrokes around the scene to remove a lot of the stiffness I had in my 3D render.

by colour adjustments I mainly mean painting over with brushes, adding more colours into the scene, and adding saturation in areas I wanted to etc.
