What is the context of the word 'rather' in this sentence?

This sentence is awkward. It tries to use the formula "rather X than Y", but X and Y are not parallel, so it gets confusing. It is trying to say that it is Willis's "attractive features" make him look good, and not the bloom of health such as David displays. The problem is that what the words on the page say is somewhat different from that. They imply that it is conceivable that David's looks could have a bearing on Willis's, which is nonsense. Change a few words around, and it makes better sense: "Willis was good looking rather from attractive features than from the healthy good looks you see in a man like David."
