Fairly simple retexture of just the blocks.
Featuring:

• Not-Ugly Cobblestone
• Interesting Cloth
• Windowless Doors
• Runed Lightstone
• Badass Torches
• Black Sand
• Brambles (for cacti)
• Rusted Iron

Note: I used the Painterly terrain.png as the base, and did not retexture some things.
Therefore, the bookcase texture, the ice texture, the tilled dirt textures, and all plant textures (except cacti) are borrowed from Painterly Pack by Rhodox.
