The structure and beat of this mix is very professional, melody hooks are very good too. i cannot sing but I think Nicki has potential to be a good singer, she/me may need some training as some parts sounded a bit flat, but pitch was not the problem they need to imagine they are getting excited about something, e.g. just won the lottery when repeating a vocal hook line. This is of course all in my opinion, and anyway I cannot sing much at all, but I think you would be at number 1 if that the vocalist had done this. Afterall the type of break beat in this instance with the catchy synth line is party/event music. The "deadpan" vocal limits this to being an excellent early evening play only.
