Re: Lucano's first attempt
I like that their directionality leads the eye to what could be a focal point in the bottom right hand corner. Don't miss out on making the most of this when planting or positioning the rest of your hardscape!
Also worth considering what this will do in terms of visual balance. Offset the focal point with visually 'heavy' elements (larger / darker plants, rocks, etc) on the left and I think you could be in for a very striking composition.
Excited to see where this is headed!
