The progression is nice. Maybe adding some different rock types could help break it up but I get it that you may not have had enough time. The shop ui took me a while to notice. It's just really small and doesn't stand out too much. Spinning didn't really play a big role since the drill doesn't actually have to be facing the rocks to mine. The art is nice. Not sure what's the extent of your work here, but it really works together well. Not bad!
