A tattoo will be painful pretty much anywhere you get it, but it's true that usually the foot is a lot more sensitive than other places.
My only advice, aside from doing all your research and making sure you are prepared, is to do this at a time when you're not so busy and you won't have to be wearing socks and stuff. The first week after you get it done is the most crucial time to care for your tattoo in order to make sure the ink doesn't get messed up or that you don't get an infection - so if you're getting it on your foot I imagine it might be better to do this when you know you'll be relaxing at home most of the time, or something like that.
It's a pretty cute tattoo, by the way.
