Just wanted to say thank you so much for the considered response. This is all extremely helpful in terms of confirmation / perspective / wisdom. I'm a big fan of 3D modelling too for different projects and I'm still curious about the idea of paying a scanning service for these sculptures, which are more on the artsy / detailed side for better or worse. But in any case I'm excited to learn more and start modelling and printing. Thank you again, this is all hugely helpful and encouraging!
