the doorway to the rainbow realm

here's a really colourful pic of my YGO gx oc aya.

she's dreaming and is taken to the mysterious place that is the rainbow realm, she suddenly sees a doorway appear and out of it comes her mother's voice.

she's tempted to go through but is scared because she realises that her mother told her not to go into this realm but why is her mother calling her? and should she go through? will something happen to her?

anyway enjoy it!!! please comment!!!
