Self writing and editing is a good way to improve writing skills, however if an expert writer gives feedback and suggestions to improve the weak points on writing is the great way to write better.
Is there any online platform or ways to get feedback on writing?
Hi Ayush, Sumanta here, I am answering you because your idea seemed to me very interesting. First of all, there is no such online platform that can help you improve your writing skills along with offering you a critical estimate of your writing.
Secondly, if you search offline, you can go to a local reputed English teacher who ( may charge you money) might help you.
Thirdly, if you approach a seasoned writer, he definitely will not pay heed to your queries.
Moreover, if you approach a fellow blogger, he may misuse your article ( chances are high)
Finally, find reliable friends and bloggers who possess essential knowledge of the English language, they may offer you help.
Last but not the least -
your English sounds good.
