I'm having difficulties with a sentence (and others like it) in the prose of a story. I've heard a lot of advice to both remain consistent with tense but also to not be too rigid about it. Could someone please advise whether or not a sentence like the following would be considered correct if writing a story in the past tense?
His secretary Ivy, holding her head up with one hand, slowly spun the Rolodex with a level of boredom fast approaching insanity.
My question is specifically regarding the tenses of holding and approaching vs. spun, which are obviously different, but does that affect the sentence in a negative way? I realise I could write something like the following:
His secretary Ivy held her head up with one hand and slowly spun the Rolodex with a level of boredom which fast approached insanity.
But before committing to a story-wide tense parsing, would like to know whether it is entirely necessary to do so.
(In this example, Ivy is being introduced, if that makes a difference at all.)
