Hope the screenshots of shading help to answer how I add shadows that many wonders..? XD;
Tried to find a nice size that isn't way too small that still shows the details (I'm hoping) yet can be arranged nicely...actually the last one was coincidence (didn't really count but the number worked out fine in the end)
And yup, there's bunch of small squares with colors that indicates the hues that I used in the steps.
Should have added few more spaces in between of each so-called steps since it looks squished...=7=;
