Nala and a Skull

Request from Jogu I was to draw Nala, and this is in fact, probably the first pic where I go seriously in for drawing her, and the first pic with her as main motive I ever have done XD Just go on and look around the gallery, the only nalas are just little "blah"'s I scribbled up in a hurry x)
I ended up liking this one pretty much though! But I have no idea of what is the meaning behind it xS But its teenager Nala(at least it was supposed to be) and she was a teenager under scars reign, aaaand I think the gazelle skull is a nice symbol for that... era.........
hmmm, what is nala thinking? Share your ideas
