Font issue

I used the Frutiger C45Light(bold)11pt size now, thats the font I am using for my body text throughout. Did not want to incorporate a completely new font because there are already 3 fonts I am using in the design.
But Smriti advised to use a serif font because that would go better with my illustration and said it doesn't matter if I use a separate font only on the map.



















One more feedback was to change the header title 'chasing the cultural monolith' as it is too academic and not creating any interesting positive impact on the viewer. So I had been told to think something poetic and simple.
