Change the Kanji to; 薔薇龍, 薔薇の竜 is a bit too literal and 薔薇龍 is a lot better.
竜 is a simple version of 龍, but I would say when paired with the notoriously difficult Bara (rose) Kanji the more difficult character pairs better.
Plus, the Yakuza games Japanese name is 龍が如く (Like a dragon) and that is sufficient proof which is cooler.
