This is mainly directed at professor Sterbini (whom I think handles all the things of the VM?):
Are you sure you've updated the files inside the VM with the files from the new .zip? I've tried running my solution on the VM but the test random-5 raises me an error for the first pixel (it says it should be (0,2,88), but that's the x-value for the magenta rectangle, which should be the last- shouldn't the right pixel be (0,0,46): the x-value for the beige rectangle?).
