Seeing her in actual MLP style, I actually think she's adorable. I saw the toy at walmart, and it was just a recolorization of Twilight Sparkle. I swear, every little kid down that aisle thought I was crazy as I was angrily muttering at the ponies.
Ah but, it's actually not unoriginal and dumb. He/she drew it differently then most draw Dewdrop Dazzle, which is an exact recolor of Twilight. The lines in the mane and tail are different, as well as the style. If you notice with other artists that draw Dewdrop Dazzle, several of them actually braid her hair, or do other things to make her stand out.
Or you could keep going on about it's just a recolor with no apparent fanbase.
(Totally not that my username on some websites is Dewdrop Dazzle and I always play as Dewdrop's color scheme when I play as Twilight in Fighting is Magic)
