I downloaded the classic textures because I prefer them instead of the new ones but a lot of the texture are not right.
I expect the textures to look as if they did before the new textures came out.
What actually happened was that doors were 2D, fish still have the new textures, and the textures are significantly darker.
You can see this for yourself by downloading the classic texture pack uploaded by Minecraft and looking at the doors, the fish, and the grass which are all darker than before.
