It is important to know one's limit, and your certainly set yourself against quite a challenge.
I see some of what you mean about anatomy, but I honestly impressed with your use of a smokey almost dream like quality to make the unnatural seem fitting.
Like the little glints of light and cascading rainbow ribbons definitely give a strong vibe.
The positioning of the arms, and the incredible profile of the face also are quite an achievement.
Thank you for making this.
