I agree with the crowd, the second one has a more balanced composition and still works with the narrative you wanted to plug. I think this is a great option. Just in case you want to try one last option, this is sort of what I had in mind.
Either way, though, make sure the lighting matches the environment, and I would suggest having her hair trail behind her a bit IF she's going to be in motion (even though it's just a snail >.<), but if she's going to be sitting still maybe she should use both hands to play the pipe?
