What about finding a band?
Even if she is still a very begginer I've seen that playing in a band can help you improve faster and learn other skills necessary as a musician (specially for drummers imo) also I made my best friendships and had the most fun while playing in a band.
PS: In case you havent done it; swapping the drum heads for good "brand name" ones can really improove a cheap drumkit, that and new cymbals (cymbals are the weakest part on any cheap drumkit).
