This was such an original plot: I enjoyed this take on canon with the next generation, etc. Draco's situation was a nice addition. Harry's reaction to Ginny's scarf was nicely done. However, I do think at times the dialogue was a bit out-of-character (Snape's use of 'really' and 'awesome', for example). I hope that you don't take that too negatively as just a bit more careful editing would fix that.
