Preloved, if they launch a mobile app

Preloved.co.id, an online e-commerce site where you can buy or sell any preloved item. I'm exploring what if they launch a mobile application. So here are my final idea exploration.

If you have something in your mind regarding my design, any feedback are welcome!
