Im a programmer and im finishing up my first app! So, i decided to have some fun and try to design my own logo(first time)[![enter image description here][1]][1]. The app is a app that maps events in the city of Skopje, Macedonia. Give me some critiques or advice ( except straightening the lines around the road and hill). 

 1. 1.Is it too childish ?

 I feel like its a bit too childish and i am planning on adding some stuff in the blue area, just not sure what, advice?  Keep in mind this is for an app. Its going to go on the logging screen.Thanks!
