What a beautiful vector! I like the idea of having her sitting on a map while she's also looking at one, but it's glaringly obvious that the map she's sitting on is a stock. She looks like a sticker put over a piece of paper. Try and find a way to make the character and the background blend together a bit more. I don't particularly care for the top half of the background. It's too empty [and just white! Why just white?!] with only a few buildings in the background. Try a different color to give it more feeling and add more buildings to break up the emptiness. Finally, I don't think you need the series logo in the corner. It's a cheap way to fill space and I think it would look better without it.
