Just checked this pack out today, I like it so far! It's nice and clean. One small issue though, the stone is so dark that it makes coal ores a bit difficult to see, maybe make the coal ore a bit darker or the stone a bit lighter so it stands out more? I like how smooth the stone is. Also liking how the wooden shovel and sword look, it's cool when the material has an effect on the design so that you can quickly tell apart something made from wood with the same tool made of iron.
I understand where you are coming from, the ores are actually just temporary for right now, I do have plans on changing them, and I am glad to hear that you enjoy the pack.
I recently added many new textures including wooden tools, stone and tallgrass CTM textures, and item frame background texture. I have not yet added them to this page but i will shortly.
Hopefully you like the massive update! I only added a couple new textures, but now you can vote each week for new content, and I will also be adding a minimum of 3 textures a week! Also, I want to change the way I display the updates, any preferences?
For the time being yes, the Gui will be the same, and I am glad to hear you enjoy it!
