Tin Man

I wanted months ago to do the Wizard of Oz as an Avalanche topic, but everyone was busy, so I tried it out on my class instead. I had a suspicion that I was overtaxing my class, work-hour-wise, so I decided to do the assignment to test how much time it would take. I limited myself to one hour per week of time they were working on it, to compensate for differences in speed and experience. So here's how it progressed, hour-by-hour.
Hour 1:












Hour 2:












Hour 3:












Hour 4:













Hour 5:












Last Hour:












At this point, I'd used up the allocated amount. Since that Time I've spent a little more time on it. This represents about 2 hours of work:












I have one more version I'm still improving on---I'll post it when I find time to put those last finishing touches on it.
