I'm trying to improve my English as soon as I can. According to the online English level exams, my English level is between B1 and B2. I want to upgrade it to C1. Therefore, I write a diary every day. Also, each day I'm trying to write more complex sentences. While I was trying some sentences like that, I couldn't be sure of the sentence I made.
Basically, I just want to say: "I can leave a little irresponsible image on the people's minds.". Then I want to write a little detail about people: "people who assign the job".
My sentence: I can leave a little irresponsible image on the people's who assign the job, mind.
In here, I am not sure at 2 points. The first one is "people's", and the second one is ",mind". Should I use comma(,) before "mind"?
Can you please help me? Your help will be really valuable for me. Thank you very much in advance.
