Can someone check these sentences describing Mr Gradgrind?

Thank you very much in advance.

Mr Gradgrinds's appearance mirrors his beliefs. His eyes contain no light as the square forehead containing facts prevents him from seeing any. His mouth is not more than a hard line as nothing more is needed for the facts to be dictated to the students with his equally uninspiring voice. His head is distorted by the excessive number of facts it stores, and his hair only protects his scalp from light,it doesn't provide any grace or aesthetic appeal.

It's fine.

Sure, I can check these sentences for you. Here's my review:

"Mr Gradgrind's appearance mirrors his beliefs. His eyes contain no light as the square forehead containing facts prevents him from seeing any. His mouth is not more than a hard line as nothing more is needed for the facts to be dictated to the students with his equally uninspiring voice. His head is distorted by the excessive number of facts it stores, and his hair only protects his scalp from light, it doesn't provide any grace or aesthetic appeal."

Overall, the sentences you've provided are well-written and effectively describe Mr Gradgrind's appearance in relation to his beliefs. However, there are a few things you can consider to make them even better:

1. In the second sentence, instead of saying "as the square forehead containing facts," you could say "due to his square forehead filled with facts." This helps to clarify that it is the forehead itself that prevents him from seeing any light.

2. You can revise the third sentence to make it more concise and easier to read. For example, you can say, "His mouth is a hard line, sufficient for dictating the facts to students with his equally uninspiring voice."

3. In the fourth sentence, instead of saying "distorted by the excessive number of facts it stores," you can say "overwhelmed by the abundance of facts it holds." This change helps to convey the idea that his head is burdened by too many facts.

Overall, these revisions will make the sentences clearer, more concise, and easier to understand for readers. However, feel free to use or modify the sentences as per your preference.
