code:OK this is slapdash analysis, but it's enough to illustrate my point: this sentence is way too complicated, particularly for a story opening. There's modifiers all over the place, and the reader has to keep it all in his head, them somehow match up all those adjectives and adverbs with what they're supposed modify. Some readers won't have any problem with this, but many will. The usual fix for this kind of problem is to break the compound sentence up into a sequence of shorter sentences.
