Honestly, not too bad with the art... but she looks like a lighter Izzy-Sonic-Recolor character with some clothing from Skies of Arcadia.

Natassa's design didn't change much until very recently. When she did change, her appearance and colors changed, but I felt like she should retain some of the cream color in her design.
You'll notice that Natassa has the full set of Ei-Ei jewels. The final jewel, the Soul Jewel, is the same color as the user's eyes. The inner part of the ear is also the same color as the eyes.
