Backyard landscaping

Remember my Backyard ideas post, where you all kindly helped me decide to create a feature garden in the green highlighted section? Well... I completely forgot that we need to have a 1m wide strip of concrete all around both the house and the detached garage. This means that the shape of the "feature garden" might need to change :(

So what do you think of our new "feature garden" shape?

Or should we perhaps widen the concrete driveway, in order to have a triangle shaped garden?

Look forward to reading your feedback :)
