Is Naina's ability to "see things" that you mentioned in a previous entry basically an increased sensitivity to detail? (I've never watched Sherlock, so I wouldn't catch any similarities, sadly.)

It is highly sensitive observation, in a way.

It's a bit hard to explain, if you don't have it. Let me try.... A person's character is essentially nothing but the emotions that drive them the most - pride, anger, resolve, sympathy, etc. Furthermore, a person's facial expressions and body language reflect what they're thinking at the moment. To some extent, anyone can pick up emotions and thoughts, especially for close friends.

People train to be able to read body language and facial expressions to a greater degree.

However, I, and consequently Naina, can read a person's face without training. It's something I've been able to do for years without really thinking about it. I always assumed everyone could, you know?

Naina is a precocious child and shows this to a high degree. She can read any person like a book within five minutes of meeting them. She can tell you their secrets and worries, the truth behind what they say and what they don't say. She knows too much and always has. And that's her curse.

Just like Sherlock Holmes could tell a man's profession and personal history through telling physical signs.

I've never heard of that ability before, but considering studies have shown you can read emotions even if you're blind, increased empathy doesn't sound far-fetched. I imagine it will provide a lot of plot opportunities for your story.

Oh, it does. It's the basis for the whole story.

It's part of my daily life so it only made sense to write about it. It's not always a fun thing to have, but it does grant certain gifts.
