To answer that, you have to become familiar with the many different types of dragons. There are Western dragons, usually associated with being evil, being able to fly and breathe fire. Eastern dragons, on the other hand, are usually noted for being good, lucky, wingless guardians of nature. Even among these two main types of dragon, though, there are many variations.
It can take a lot of research learning about the different types of dragons to find one that fits your own personality. Remember that no one is going to judge you for the dragon you choose - even if Eastern dragons are supposed to be evil, it doesn't mean you are if you choose one for its beauty. Here are a few places that can get you started in your search:

Remember, whatever dragon you choose is your decision. I hope these help to give you inspiration as you search for the perfect design. Always keep in mind that no tattoo has to be exactly like the original drawing. If you see 2, 3 or 10 pictures that you would like combined into one, a true tattoo artist will be able to do this for you. Also keep in mind that some of the full color art images are much too detailed to be replicated exactly as a tattoo, but they can be done very similar to the original with a little adjustment by your artist.
