Hexagon model to sculpty rough looking

shortstan

Attached is the model I finally created of a sailboat hull for inworldz.com. I find that the model done in Hexagon using a sculpt sphere looks
better than what is being created either in SL or inworldz with the exported map (see photos) . Anybody have any suggestions what I can do to make this look as good as the Hexagon model does?
