Lovely smile for starters - you can see the happy eyes, which is a give away that's its not forced
SO the lighting
Well you seethe benefit of being off camera straight away, a little more 3D, shadows below her jaw giving that impression as well as a her cheek on the right being a little darker due to the light direction. all good.
all in all, very pleasant and well done for a first attempt.
Suggestions for a more creative shot...
well unless you've got really long arms, you can't really get the light source any further around her to get a side lighting effect - imagine the light at 8 oclock on a clock face, your daughter in the middle and you at 6 oclock. That would give more shadow and more drama. You could maybe use a wide lens and get in closer to do that.
Height - hold the light up high, again at 45 degrees but fro mhigh up and pointing down - that's going to give a classic look, a shadow going down her face, almost "rembrandt" lighting
Maybe try holding the light almost directly above her at 6 o'Clock - this is used a lot in fashion and if you get it right it's very flattering.
To get very directional light, make a "snoot" out of newspaper by wrapping the newspaper around the flash and sellotaping it secure, then point it at a vertical reflective surface (white wall, tin foil etc.) - all the light that his your daughter will now come from the wall, not spill from the flash, so it looks like the light source is from one direction.
A few things to play around with when you've got a TTL flash chord
