Entry for Adobe XD Playoffs

lol I couldn't submit this probably because I don't have the invite thingy, but I don't really know cuz I never saw the rebound button.

After looking at a few submitted designs, I wanted to make something simple and basic (not because I didn't like the other designs, but simply because I am an amateur and not capable of making such complicated designs at the moment). Anyways, I heard of rule of 3, around 3 days ago. So I decided to go overboard with it (since, again, I didn't know any better). I divided the phone into 27 segments on both axes (cols and rows) such that it was divided into 3, 3 times. I tried to design it according to that grid. I'd love to hear some feedback, or knowledge/resources for someone like me.
