I have a Minecraft Texture pack in the works that is nearing completion.
Here are a few screen captures.
In the Nether I got rid of the pink flesh colors and added some green to combat the red and orange overload.
My main goal was to try and keep the general feel of the original but to do something that looked better and was kinder on the eyes.The originals had a lot of unnecessary noise added to them to make up for lack of detail and were often just bland or poorly made.
The pack will include texture and GUI changes for the entire game (excluding water and lava) and was made at the games native resolution to keep issues to a minimum.
Look for it within the next few weeks!
