Hi, I want to say that John looked at his instructor skeptically and what came out of my typing was this: John gave his instructor a look that was highly skeptical. Does the line make sense? "John gave his instructor a look" makes sense, but does, "a look that was skeptical" make sense gramatically? I assume throwing in "highly" doesn't change anything in terms of grammar, is that correct? I know it's not the most creative way to say it, but sometimes words just come out of my head like that and I'm always worried that not only is it not the most creative sentence but also an incorrect sentence. As always, if anybody has a better way to describe a "skeptic look" (which I'm sure there are a million other ways) and would like to share, I'd love to read and learn from it!
