Hello Farhana, Before I share my opinion, I will clarify that I think the previous observations and suggestions from other helpers are great. And you should consider them, of course. In my opinion, however, your sentences are perfect IF you intended to play with language. What I mean is, that there is a play with words which I think is interesting.
