To get a tattoo on my wrist, not too big but also not tiny

I want to get a tattoo on my wrist, not too big but also not tiny. It should have a triangle and a hexagon involved, ideally underneath each other so that eventually a third shape could be added. It should be fine line and monochromatic, and both minimalistic but also artistic and it can have some flower and stars elements in it. Those symbols represent space missions so some space things can be in there too.
