While I can draw fairly well, for myself I would still like the CV. It would be useful for when I cannot illustrate properly what is in my mind and thus having a image constructed to use as a base can help get past this.
For those that are wary of it because of its appearance. While not a perfect fit, try taking the image into something like Photoshop it is fairly easy to change the style of a image to emulate a different medium.
What I am wondering is if/when it comes out how will they keep up with new options? It isn't as simple as putting in data like the CB or Compendium, so how would they handle new weapons, new races, etc.
