First of all you see children cartun with hindi subtitle, you can improve hindi

If you want to write Hindi correctly, only way is to learn to write Hindi fonts, since it's very different, it can't be explained simply writing Hindi word in English....ofcourse Hindi fonts i.e. vowels(maatraas) & consonants(shabd) are almost different. You have to start from the start. May shortcut in speaking but not in writing.

learn to write KA, KHA , GA , GHA.. etc, then learn writing simple words like Ka+L = Kal, Cha + La = Chal, then learn how to write "matra" i.e a A, ei EI, etc.. and using them in writing. This could be the simplest way to learn to write Hindi. Regards, karan +91-9899551131

Just learn to write it fast :)
