And it seems that the most popular guesstimate of what my model set – combined from Facebook and Twitter – was unexpectedly the "Old Ruins" set. Perhaps that’s a most wanted set.
I’m not, however, working on that right now. I’m still keeping it under wraps until I have a few more models. The screenshot is an example of some of them so far. As I gain more confidence in 3D modeling, I think I’m going to attempt on doing an old ruins set.
