That's a good question, and it depends on what you want out of the tattoo. Here's a picture that was posted some time ago on another thread on this forum:
Getting tattoos that go together more or less like that...a sort of classic Americana look...shouldn't be too hard as long as you get tattoos that go together in broad stylistic terms. In this case that means black outlines, strong silhouettes, black shading, and bold colour. I think an advantage to getting tattooed like that is that if you want to have a representation of travel on your body, there are a lot of great tattoo shops all over the world and you can get tattooed at them. It's better than getting a stamp in your passport.
If you want something more like a single coherent design incorporating various elements, that would have to be worked out with an artist. In my opinion, what you wrote in your initial post is far too much to put into a tattoo and have it look good, and since your artist would probably try to give you a resolved design, adding to it later could be difficult. If you look at these beautiful coherent Japanese sleeves you'll notice that they're often fairly simple: they'll have an animal or a creature, a plant or flower, and a background (wind, water, etc). Regardless of what you want out of your tattoo, I think you should look at as many good tattoos as you can...look at the thread here about what makes a good tattoo, look at the latest tattoo lowdown and monthly contests, follow tattooers on Instagram...and figure out what makes tattoos work as tattoos and go from there.
