After falling over twice after waking up, I did a bit more work on the Dirt, Stone and all Ores
I think that the ores should look a little more natural, but if that's not your thing, it's fine.
Right now the ores look kinda flat. I see you've tried to add some shading on them, but it needs more contrast (the lighter parts lighter, and the darker parts darker) You also need to think about weather your ores will be sticking out, or imbedded. Because right now, as I said before, they look flat, like they were slapped onto the rock.
