ideas for a back piece

My friend is having her anniversary this month and wanted a back piece done. She told me to cone up with something.. Any suggestions? I think I'm ok, but I've been told I'm good. But this is major and I'm really excited!

Maybe you can get inspiration when you use google images for back or shoulder tattoos? Often real tattoos can give great inspiration for adult designs.
It does not have to become as intricate as real tattoos are, but it can give some ideas.

Thanks!

a lot of times I try to find out something about them... their likes... I had a couple who were getting married in Hawaii... both the husband and wife wanted me to do their henna before they left for their destination wedding... well I played off their Hawaiian wedding... the husband ended up wanting a massive sea turtle... the bride did a lot of Hawaiian flowers filled in with paisley designs...

so maybe find out something that was special about their wedding... or honeymoon or about the couple in general and then play off that

OK. We talked a lil..she's trying to get off cheap cuz of whatever her personal reason was..smh..then she had the nerve to tell me since its not permanent not to charge her too high..the only reason she's doing this is cuz she is too scared to get a real tattoo..if she really wants it..I'm a go hard and make it look worth time n money..but I'm kinda put off now..
