I personally don't like it as it still looks computer generated and I certainly wouldn't put it in a portfolio. I also agree about the lack of detail, I think it needs more. I've yet to see a Photoshop filter that I like without a lot of additional post processing. Nothing beats an actual hand drawn image but some of the 'Dennis effect' efforts from the past have come close. I would look up some old threads on this and the Google forum for examples.
