If you "Watch" someone, you will get a deviantWATCH message whenever they post a new image (or if they post a new Comment in their DA blog, if you Watch their blog also.) "Watching" someone is sort of like Following them on Facebook or Twitter.
You get Feedback Messages if someone posts a Comment on one of your pieces. I think you also get them if someone posts a general comment on your homepage.
This is beautiful, I really love your work. Incredible unique and original.
I'd love to see some pictures of your sculptures from different angles though, so I can see how they're constructed. It's hard to imagine them in 3D space like this - I suppose that's kind of the point but I'd still love to see how they're put together
