"For those who are interested, Freestyle has evolved into Neobarok : http://facebook.com/neobarok3d  and it will be released as a free sculpt-assembly application by the end of 2015.Neobarok is a much more advanced and complex software, with features beyond mere sculpting, but at the same time it is more intuitive to use than Freestyle.
