Hey there!
Let me give this a try :)
The turquoise waterfalls fell down the mountains quietly as they flowed into rivers and streams throughout the land. The faint sound of calm, still water echoed for miles around, and the smell of salt flew through the air.
Ashley Lynn sat perfectly stationary on a gigantic, grey boulder overlooking the tranquil scenery. She patiently watched and waited, for she was unexplainably parched and in excruciating pain, waiting for a heroic rescue.
At last, the day came. A large boat came to the deserted island d to find Ashley lying on the rocks, alone and desperate. The Captain ran out.
"Mate! You alive?" He said with a strong British accent.
The girl looked up, and her face lit up.
"SÃ, mi amigo. Muchos gracias."
Although he didn't understand, the captain shot her a smile and carried her to the ship, He ordered his servants to bring her food and water, and as they sailed away, the rainbows across the island shone brighter than ever.
Hope this helps, let me know if it needs some revision :)
