Interestin.. like tad said vary your rock size. You have a big open spot on the left corner where it goes gravel to mulch put a plant there up againist it. Take some of you stone behind it out and blend plants between them. Do you have pics during your construction phase all i see is a tub then its finished..lol. Im with tad there is no need for the tub, a wider piece of liner would have been cheaper. That tub will eventually develope a crack.
