I think I know what you're referring to, but in this case I'm not sure whether it's mostly due to post work or just a peculiar render result. But Elements should certainly be able to get you some aspects of a "sketch" look. In Photoshop I use the Artistic, Brush Strokes and Sketch filters - I'm not sure if Elements has these though. "Reticulation" is particularly cool in my opinion, and if blended with the original image it would probably create the effect you want.
