To improve your writing skills at first you have to put that in mind that keep reading new things by reading your mind will become open and by that, you will get new ideas which will help you in writing good things.

To improve your writing skills you should write daily as it will help you to increase your writing skills. You should keep practising and after one point your writing skills will become improved and by doing the practice you will also know where to use a comma, inverted commas etc.

You should make a daily habit of reading and writing to become perfect and to improve your writing skills. I also improved my writing skills by the things I wrote upwards.
