The link you provided says the pattern is imported from the Netherlands. It also says foundation pieces not included. If the pattern is imported, I would make darn sure it is in English and even then I suspect you will have trouble. I consider myself an experienced paper piecer having tackled MC, FG in a circle, NYB and many others. I would consider that pattern, just looking at the link you provided, a 5 on your scale. It is beautiful but I'm not sure I would tackle it. Additionally it is pretty expensive for just a stand alone pattern.
