Hi everyone! My mother is redoing her guest bath (pics to come) and out of budget necessity, has chosen plain tempered glass shower doors. They are directly opposite the door when you walk in so the shower gets a lot of visual attention. She has asked me to help spiff them up a bit by etching them, attaching photos via image transfer, window cling film,etc. She's not afraid to take risks.

Given that I'm not very handy or crafty, despite her faith in me, I need help. I've attached a basic layout. Any ideas on how to give them some visual punch?
