My yard

It's approximately 10000sqft. There is minimal landscaping and a lot of grass.I have river views to the left of the house that I would not like to obstruct. I'm trying to lessen the amount of grass I have to mow and get the location of beds and plants laid out if possible. The back yard is another story. It is tiny and hilly. I would love to add some retaining walls to extend it out
