I am just blown away looking at this. This is a real gem. I hope that you have a fantastic place to display it. I learned really great techniques from this build thread that I look forward to trying out!
I like the goal to bring in millenial'ish folks-- I was born in the early 80s and on paper fall into the early years of that generation. The real challenge for "us" is the time to build as we are all early to mid-career in our age group. But, getting these folks now means dedicated modelers later!
You really did justice to your subjects--nice builds!
It is really amazing how the Canon kits come out--especially considering that they are free offerings, and they offer quite the variety of uncommon subjects like the Sagrada Familia.
