Another portfolio question...

Last time I asked about my portfolio I accidentally distracted people from my real question, which was what I should paint in the time I had left before the con. Based on replies, though, it seemed like I needed a piece with a complete background. I decided I was low on people, and had no female subjects, so I painted the samurai.

First, is she good enough to take with me? If not, is there some way to improve the piece so she is?

Second, I've got less than a week - is there anything in particular I should try to paint in that time? Another landscape? Some horrible monster? If not, I'll just try to get the Avatar of Silliness done in time.
