Thanks to X17, he showed me how to make a texturepack and how to share it.
1st version of this texturepack. It contains textures of simple blocks, like wood or stone
2nd version of this texturepack. It contains all around ores, for example, lumps and ingots
Nice 2D style
Although it still lacks a lot of textures it seems to have the potential to become a TP with a very unique style. I'd suggest to be a bit more consistent throughout the textures, but so far I very much like the 2D style of the current textures.
