I would much appreciate that if other researchers will contribute or share their ideas , links , web tutorial or any personal techniques to improve the writing skills at the doctoral level ;which will be helpful to write concisely and authentically.
The simplest way is to read papers, articles, and theses in your field from reputable resources. The more you read, the more you get to know the language, phrases, and structures that are used in your field of study. Remember, the more you read high quality of papers, the better skills you gain.
There are a lot of websites that provide tips on improving writing skills. But, from my experience, it is better not to start with those websites until you are familiar with the writing requirements in your field.
You can also attend workshops on writing. Or seek for a one-to-one session to evaluate your writing skills. Some universities offer this service for free to their students.
Most important , practice, practice, practice. Writing improves by practice. Don't hesitate to write on any occasion and seek for feedback. Be open to all sort of comments.
But, before you begin any sort of writing sessions, you should know what sort of skills you need to improve or learn. To clarify this, I will share my personal experience. English is not my mother language. When I first started my PhD journey, I did not have any issues regarding grammar and structuring sentences. However, I wanted to focus on comprehension and the flow of the words. My educational background was in computer sciences, but my PhD was in managing information systems; i.e. social sciences. So, I was not familiar with the writing techniques in social sciences. I developed my writing skills in various ways. One powerful way was through attending creative writing sessions with novelists. This has improved my writing a lot.
So, you should first know the areas that you would like to improve, then look for what works for you. All the best.

Thank you so much for your valuable responses but after some efforts ,I found what I had missing in my writing and some of the books also helped me how to improve critical writing.
