Brave Fencer Musashi was a great game. It was so bizarrely fun and awesome.
Given the ancient graphics and the nose-less style of most of the characters, there was a lot of room for trying to imagine what the characters were supposed to look like. I like the choices you made for her features: she looks as sadistically happy as her boss fight told us she was. :)
I also like the weird balance you struck with the style and exaggeration. It's funny that you gave her a nose and fuller proportions, but you then you made her hair more flared than in the original.
