beach biome rework

I am a Minecraft player since 2013 and I have had an idea to improve the beach biomes in Minecraft

These are some of the ideas I have to implement:

-pink sand or variants
-palm wood or similar
-sea shells
-crabs
-pelicans, seagulls, etc.
-beach sounds
-rocky structures on the coasts

These are some of my ideas and I think they would look great with the content that was added in the aquatic update.
