decoden phonecases

im planning on getting a new phone by the end of the year and with a new phone i must get a new phone case (Momo try not to drop ur stuff challenge IMPOSSIBLE) and i was planning on getting a custom decoden phonecase ^_^

i made like a mockup(?) but i feel like im missing something ... like it feels lacking compared to other phonecases ive seen but im also scared of it being too cluttered T_T
