I also can help critique, more than just a 'good job' comment every chapter. I also keep an eye out for character consistency, paragraph structure, as well as what works with the story and what doesn't. I'm no grammar-nazi, but when you are writing, grammar comes after the story's finished. I'm here to help you with anything you need in a beta-reader.
Contact me either here or messenger me personally. Thanks, and I hope you have a wonderful day!
