I went for an autumnal scene
* Duplicate your existing Mal sketch image, then close it (for safety purposes)
* If not flat already Layer > Flatten the duplicate
* In Levels set left hand slider to about 70
* In Hue and Satch set Saturation to about 50
* Duplicate the Background twice; turn top layer off.
* Middle layer: Apply Gaussian Blur to about 2
* Middle layer: set Blending Mode to Lighten
* Top Layer: set Blending Mode to Lighten
* For the dark border I sampled the dark part of the tree to the left of the house.
You now have what appears to be a path starting from the bottom right, leading upwards to the left between the autumn leave(?) and then swinging right to the house
