Landscape Drawing of garden. One standard image but lawn area size and shape.

Design details: I need 4 drawings doing to show our customers how to measure an area for installing artificial grass, our current drawings are very basic and i would like them re-done to look like the attached picture... its a rough idea of what i want but to have a similar look. All 4 drawings can have the same background and on each just change the lawn shape to reflect the lawn shapes we show on our website... its the lower 4 lawn drawings that i want to be done and can be found here https://www.evergreensuk.com/artificial-grass/how-to-measure-artificial-grass-for-the-perfect-fit/

As i have said the standard image can be the same and then alter the lawn shape for each of the drawings and maybe add gravel, for example, to fill around the lawn to make it work with the standard drawing..
Ideas for the visual style: as example attached
