My "attempt" at a map

I thought going onto Google maps and just editing the colour and putting the shops logos on top would be a good idea... I knew this is my worst spread so far but I didn't know how to fix it until critique with my teachers.

So also my key area is too big as well I just noticed.
I went to class and he did say this was my worst one -which is fine. I really need honesty. I have to make my own  map (HOW???) and stylize the logos of the shops if I want to keep them in there. I think ill leave them out because It looks a bit tacky...

This is just a big mess.
