I don't know, I think you're being too harsh with the original. The new one looks great, but I actually find myself looking at the original more. Aside from the anatomy (foreshortening of her arm looking a bit off), I personally think the overall character design and color scheme is more appealing here. The different shades of hot colors on her horns, hair, and clothing look quite nice. I imagine her as a demon associated with the Sun. Was that intentional? I also think these colors blend well with the pink background.
I'm not sure why, but the yellow-orange shirt gives me the impression that she used to be one unpleasant store clerk.
