Mas allá del Armario - Enchanting Book Cover Design

It generates a cover for a story called "Mas allá del Armario, donde los secretos despiertan", referring to three friends who experience a time travel through a closet door, which is actually a portal, to a fantasy world, where, to get out they must complete five challenges, in the end they manage to get out by successfully completing the challenges with a key that is given to them; but when a voice comes out from inside it prevents them from leaving because one of them had a gem, of bright blue light, that gem is the heart of that world. When they returned the gem, the three of them together, became guardians of that portal forever.
