Hi Daz, Welcome to the forum!
I think what your best bet would be is to decide on something that means a lot to you.
What kind of things do you enjoy?
What strikes your intrest that you could stare at for hours?
You want your tattoos to have meaning behind them otherwise you’ll end up hating them.
Then, once you figure out exactly what kind of central idea or theme you want your tattoo to follow then make an appointment with your artist and sit down to bring it all together and to get his professional, artistic opinion. 😀
