Tattoo ideas for my late dad?

My dad past in February & it is the hardest thing I have ever had to deal with I know I will never get over it! For the past 2 months I have been really wanting to get a tattoo with something to do with him, I carry him in my heart that's permanent, but I want him on me too!!! Last night I actually had a dream that he was still alive and he was a tattooist was very strange but I woke up crying and now i'm on here?

I don't want his date of birth because I don't want his death date on me!

I want something that's him and something that's me, I can't even explain what I want so I need some help

He loved music and my nick name from him is teddy I really hated it but now i'd do anything to hear him say it again!!!

Also I want the words in it "what if"

because it was the name of his fave song, was played at his funeral and 2 days before he died he phoned me and I almost ignored it! But i'm glad I took that call and some time i do think to myself "what if" i didn't? So i have these rough ideas but don't know how to put it into a tattoo.

Thank you! x
