Firstly, you can improve your English writing by not writing in capitals- it is hard to read. Developing fluency in a language takes time and practice and there really isn't a magoc solution. If you are studying alone, then do an online assessment to see the areas of your grammar where you are weaker and focus on those, and keep talking and practising at every opportunity.
