A couple people in my critique group on different occasions have commented that my sentence lengths were too similar. Some of what they say makes sense, a lot of my dialogue sentences have a repeating pattern (I'm working on that). But part of me wonders if same sentence length is something many people pay that much attention to? Most of the time what I learn from critiques, I find myself noticing in books I'm reading. But repetitious sentence length has never been something I've noticed. I see there is an existing tag for it. I'll have to check that tag out.
