I always liked her design, but the artist whom's pictures I use (Doomthewolf) draws her so perfectly nice. Especially her eyes and overall face are very alluring I think. Hips/butt are a bit oversized though, me thinks.
And yes, that's her Taomon form. To be honest, I had to google that up, as I didn't watch "Digimon" long enough to actually see her. I just thought she's wearing some kind of special outfit. But nope, you're right, she's Taomon in those. Wow, I learned something new! ^^
