It is difficult to produce a text to image prompt for Stable Diffusion without knowing the type of image you wish to generate.

However, here are examples of prompts that can generate a beautiful landscape using Stable Diffusion 1.5:

```
surrounded by mountains, lake in the middle, small island in the middle of the lake, the island is full of flowers, movie texture, 8 k, rich details 
```

```
summer day on the beach, sun reflecting off the sea, colourful umbrellas and parasols, bright sand, depth of field, film texture, 8 k, sharp details 
```

```
sunset over the city skyline, tall buildings reaching for the sky, warm orange and pink hues, motion blur, film texture, 8 k, rich details 
```

If you are able to provide more details of the type of image you would like to generate, I can provide a more specific prompt.
