The mobile app will be launched in South East Asia region. The name of the app is a play on words on the fruit "durian", hence duriana. It should be a simple and easily recognizable logo ideally looking like the durian shape as in the attachments (I particularly like the durians_v2 image uploaded). It should be simple and not too sophisticated/detailed because it will also be used as the app's icon on iOS' App Store and Google's Play store.
The name "duriana" should be written in a very simple font with no swirly, fancy lines. By "Playful" we understand "fun" and not "childish".
