Hope you are doing well!
First, you've not wasted any years. You're in your final year of CS engineering, based on which you can either get into a job or receive a project to work on your own. If you want to start your creative project, you can start dedicating sometime to it starting today. I am not sure what is stopping you from doing your creative project right away.
After completing your engineering degree, you can either do a job in CS field to financially survive and simultaneously work on your creative projects, or you can dedicate your entire time on your creative project, if it has the potential to produce enough financial help for your basic day to day expenses.
I am not sure about communication based(English) industries you are referring here. Are you passionate about these industries? How do you think this industry will help you grow your career?
