Really cool stuff, is it a plush or an art doll?

Not the art.
It is a tool of delusion.

since they're english is'nt great, its a doll. seems like a pose-able anime doll style with new furry parts custom made, and fur added. (saw someone who owns one of bureidos dolls talking about it once)

Well to me it looks like face and paws are something hard while everything else is soft
like most art dolls
and yea noticed. It kinda sucks that good artists dont know english Dx

To read the English can, but writing is not only use the translation site.
アートなどと言う高慢な位置の物を作っているつもりは無い。
さまざまな表情やポーズを取らせて好きに妄想するためのものだ。
表情の差し替えもフル可動も妄想の幅を広げるためにやっている。
How to write these Japanese contents in English?

google translator gives really confusing translation to that, saying art is not your pride and something

Maybe get someone to translate for you? I know dragon-x2 has person translating for their commissioners since they understand english well

Let me try to translate his previous comment...

<I don't have intention to create something arrogant what is called "art".
The focus of my works is at　broadening one's fancy.
Various facial expression parts and multi pose-able joints are just tools for it.>

I think he wants to tell you his works are less formal.

I'm also non-English speaker,so I think there are still grammatical errors and misunderstandings.
Sorry for poor English.

-Squeals- It has the same colors as my fursona!
