Only boring because there was probably a little too much shutter drag. Kill the ambient, stomp on it's throat, and throw it's carcass into the river with 1/200 and see what happens. Then go up from there as you get used to balancing flash with ambient. In this case I'm doubtful there was a great need to drag the shutter though. Where that's really useful is when you have a background you want to burn in, and use the flash to expose the subject. Here the subject is really being illuminated with mostly flash. Not dragging the shutter might also have gotten rid of that unsightly cord coming out of her hand.
I can tell you bounced this off the ceiling; that's about the most boring place to bounce from. Safe, yes, but produces flat results. Try flagging the flash (put a piece of black foamcore or even your hand between the flash bulb and the subject) and bounce it off a wall to get harder, directional light. It can make things more dramatic and dynamic. As for fill, you'll get a decent ratio from that thing she's on.
However, the image looks underexposed, particularly her skin tones. They're over-saturated. I'm going to guess that the thing she's on is actually whiter than as in the image. You should bump up the EV comp on the flash to compensate. The camera will try to make all that white into a neutral grey, so you need to tell it to put-out more power from the flash to properly illuminate your subject. In this case, I'll bet an extra stop on your flash's EV comp would suffice.
