My app called Trace. It was called FoodTruck Trace. I redo my app map and wireframe. Before I start to do a prototype, I would like hear some of your advise. How I can make this app more functional and looks better for users?

Comparing with last version, I have added two more features that the app can show fruit stand, nuts&nuts, and Food Truck locations.

Please forgive me about iPhone structure, I am still getting all the boxes fit to the iPhone app, but I have a little trouble to align them together.
