To brighten up those concrete slabs, you need to obtain some stencils, and then you can paint pretty welcoming designs on the path up to your front door.
Buy, or make, a stencil of a wheelbarrow, and spray each slab with a pink wheelbarrow design.
To further enhance the garden, it needs a focal point at the centre. I suggest a pink wheelbarrow, mounted on a plinth. A pretty wheelbarrow is wasted using it as a container for weeds.
I guarantee that no-one else in your neighbourhood will have a garden like that.
Actually you need another wheelbarrow, wooden, with holes, that you can spray pink, and plant up with geraniums, petunias, and trailing stuff, etc. And use that as a centrepiece.
