BakaArts is awesome and you've pulled off all the styles.
The first is the best.
The second is nice, but I think you should have maybe added your own twist to it and WAY too much topaz making her look weird. If using topaz I just click "clean" and turn it down to 1

The last one is nice again too much topaz but I think it could do with some darker lowlights through it. Overall not bad work man
