Well, the more you read good journals on the topics you are working on, the better you writing thoughts would be. In addition, make a habit to write frequently. Practice makes perfect, even though it is hard in the research world. Take my case for instance, I got three supervisors to deal with. Once my first draft of article passed with my director of supervisor, then the other supervisor, the reputable Prof(UK terms;)) not US) would amend the draft. In fact, he would correct the article back to sound like initially i wrote it. Maturity will makes you to come to a conclusion that, the whole research resembles to a half full glass of wine/wtr.... If your supervisor sees and would like to see the half full portion of the glass, thus, good comments you will get. If the same supervisor happens to see only the other half empty portion, thus, negative comments will follow. As a researcher, don’t worry with all this comments, however, try to get constructive comments from all the supervisors. Finally, write your work with your own style meeting the supervisor or journals requirements. Whatever it is, stay put, it is just a phase of research life. Like river tides, this phase too will pass away. Cheers;))
