How and where can I get a good Minecraft texture pack?

I play Minecraft and I want to have a real live texture pack, so I mean the water should look so nice and you can see through it and there should be shadows and so on. I think you know what I mean. Could someone tell me or show me where and how to get something? 💝 Regards, Kristina

You also need shaders if you want to have shadows:

You mean a shader, not a texture pack.

For this you need Optifine and a shader.

Thanks

Thank you very much
