For the awesome water update of Seus ptgi, I wanted to create stuff that goes well with water.  Also, some of you  recommended that I should use the "ctm overlay" feature.
That's why the "main - block" of this update is the sand, obviously.  Took quite some time, especially because I'm very new to Minecraft Texturing, I'm still learning.

All changes:

• Added Sand + Red Sand ( about 100 texture files for all overlay situations!)
• Added Terracotta and Light Gray Terracotta (I don't make all variants yet, since that's a waste of precious RAM, performance, loading times, etc.
• Added Chiseled Quartz
• Reworked Cobblestone with actual stones I collected and normal-scanned
• Added Light Gray Glass Pane (it uses a rough normal map - this is supposed to be "blurred" glas panes -  some of you wanted me to make this. Looks pretty cool.
• Adjusted all texture maps for the iron armor (Seus ptgi E8 update messed with the reflections)

Important:  

• Set Connected Textures to Fancy in your Video Settings --> Quality Options!
• Enable Alternate Blocks in the Video Settings --> Details Options!

How I created the sand textures:  
I sculpted the pattern in a bowl of fine dirt (with my fingers, haha), and then I Normal-Scanned it, edited in Photoshop/Blender and made 2 main pattern textures, which get randomised by the blockstate file. (Minimizes pattern visibility)
The overlays onto other blocks are using the optifine ctm overlay method.

The sand (+red_sand) textures consist of over 100 indivual texture files (Diffuse/_n/_s)
This is also noticeable when comparing the file size of R7 and R8:   48 vs 132 (MB)

In the past 2 weeks I learned some techniques on how to get proper normal maps from real life objects/materials (no auto generated normal maps from materialize/CrazyBump,   no photoscanning)     

Next update:  I think I have some great ideas for some shiny blocks, not sure if they turn out well. (Gold, Iron, maybe diamond)   But I'll go with whatever I really want to work on. I'd  like to create more blocks that are quite complex and time consuming (like the sand).
I really need to remind myself to make every block something special.

Next update in about 2 weeks.

Hope you like it!
