Art is art. So ya, it does belongon da. If he advertises it for sale is his choice. Deal with it. The photos of the amazing sculptures are amazing temselves. If you realy have that much of a issue with him wanting to sell his beautiful art, then don't look. Simple as that.
Not everyone that sees a single image wants a tutorial. You did, so I helped you. (Actually, there is a link to this tut, I had it saved: hontor.deviantart.com/art/Tuto… ) I'm not the artist and it's not up to me to change the description.
