Once outside the church, I looked beyond the bicycles leaning against an old brick wall.
I think leaning should be leaned. Looked/leaned. Then maybe it would go leaned up against an old brick wall. I don’t think this is an insignificant issue. Publishers care about these sorts of things. At least I’d think they would. At any rate, I care.
I know, right? This is what I’ve spent my morning doing…thinking about this one sentence 😛
