Here's a look at how much of MCH is done. You can see on the closed section I have the orange outline. I'm using the footprint of the opened version to help guide the look of the closed one. I thought originally that I would be able to copy paste the 6 hoppers on the closed version but they're all slightly different, but once they're done and the backgrounds between them are done I'll move to recolor the whole thing.
Edit: Okay I've finished it up. Was able to work pretty much all afternoon and evening on it :). I'll try and start coloring tomorrow.
