Is it clear what this site is for and why someone should stay? A visitor decides in seconds, and right now the page is beautiful but says almost nothing.
The essentials are pointed to
The two things the site clearly wants to promote, the book and the book-signing events, are both present and easy to spot. The intent of the page comes through.
The homepage barely introduces Jet Li
Beyond a one-line book blurb (which is itself cut off), there is no real introduction, no career summary, and no story. For most visitors who are not already deep fans, the page assumes a lot and explains little.
The calls to action are vague
The main button simply says "About", and the largest element on the lower page is a "Be The First To Know" banner with no reason attached. Telling visitors what they will get (early access, tour news, a chapter preview) would turn a pretty page into an effective one.
People engage when a page answers their questions before they have to ask. A few genuine sentences about Jet Li, the book, and why the mailing list is worth joining would let the site convert the attention its design already earns.
