Is Doujinshi art hand drawn and Vector art computer drawn?

Well, either way, this is my first art submition. It is constiting of a mindflyer monster from the final fantasy series (I focused on FF 1 version, but it realy doen't change much from version to version. In fact it isn't to much different then the Forgotten Realm mindfligher if I'm not mistaken, but I digress.) The three people aren't anyone in particular, and are not even based on any Final fantasy character. Their just some people fighting a mindflyer.
