The point of FinishLine is to make everything good for a spot in building. It also makes everything smoother. (I got obsessed with it and my eyes hurt when I look at the original before the texture update.)

Start Hierarchy
1.0 - Blocks
1.1 - Items & Armor
1.2 - Entities
1.3 - GUIs
Enhancement Hierarchy
2.0 - Enhancing the blocks
Revision Hierarchy
3.0 - Changing some ugly things
3.1 (Present) - Changing more ugly things

Some blocks will be found in strange places, such as:
Melons/Pumpkins in walls
Redstone Blocks in tops of buildings
Diamond/Emerald/Gold Blocks as flashy tiling
Leaves as cloth
Command Blocks as computers

You can inspire your textures from FinishLine, as long as you use only ideas and/or change the textures a lot. If you used ideas or mentioned this on social media, give a link to here.
