Not only is Zach a talented designer and sculptor, he's also a master at communicating his skills, and I find him very inspiring.
What impresses me most is his ability to begin slowly, methodically, to bring us beginners on board, with the first project, and as the course progresses he builds on what he has taught us, and despite being a beginner at sculpting, he never loses me by going too fast (or slow, which is just as important).
I've learned a LOT from Zach's courses, and at the end of the day, that's what it's all about!
