You should introduced some colour. It looks almost monochromatic.
BTW, that’s a lot of concrete around the house:(

hi 10x for comments on top is my update 
This place has a great design, almost ancient - fits the corner nicely.
The overall light could be a bit more intense for me, it looks a wee bit soft - you could probably achieve it PS - great overall
