First DSG pic I've downvoted. Her face looks totally off.
Not only that: The head is also too small (at least it looks that way) and the body twist with those large funbags looks...at least unhealthy for her spine in that position.
Which to me is rare. Pixiv members don't usually critique others in public.
Thats generally true about all social communities; negative responses to anything is heavily frowned upon. Most people would rather have silence rather than (possibly) constructive criticism.
