342X: Asian Inspired Dragon Picture Book

I was hoping someone out there would have a bit of information on a book I’ve been looking for over the last 20-25 years. The book was a hardcover, horizontal/landscape style. It was highly stylized, with what I could only describe as flat/paper like art. The book had little story to speak of, with the appeal being the detailed art. I believe the book had some fold outs as well.
The little text it had was descriptions of the dragons (if there even was that). It may have served as an encyclopedia of different dragons (Ice Dragon, Mountain Dragon, Forest Dragon, etc).

The dragons were mostly Asian-like in nature but there may have been some Western ones tacked on as well.

I think it was printed in the late 80s or early 90s, but it may just have been when the book was available to me. I can’t see it being from before the 1970s, it’s just too stylized. It’s possible, but I don’t think it was.

241A: Chinese Dragons and Witches With Flying Hair

A fantasy middle-grade novel I read in the mid-80s, with a green Chinese dragon on the cover. The dragon belonged to a Chinese girl who rode it in a circus and put on a thick Chinese accent for the punters, but could actually speak English perfectly.
She was one of the magical characters helping the two child protagonists on their adventure: another was a witch who had long hair which flew about when she was casting spells. She made an illusory double of one of the children (called a Semblance) so they wouldn’t be missed.
At one point the protagonists and their flying carpet were swallowed by some kind of evil spirit that had a dark stormy space inside it. They started calling the spirit the Glutton to make fun of it, and the witch put her head in her hands as if she was despairing so nobody could see her hair flying about when she used her magic to get them out.
