User blog:Tiberius64/Need Help With a New Enemy!!!

Well, if any of you read Ad Astra 3: In The City Of Love, Phineas mentions that TerraFleet now has a new enemy species to deal with (it's a bit more emphasized in the FanFiction.net version). Well, I am working on two stories at present, the first dealing with character death and the introduction of this new enemy, and the second one is the sequel where the undisclosed dead character is revived at great cost. I shall not disclose the name of the new alien species, but I will give their characteristics: From a Star Trek fan's perspsective, I am combining the personality elements of the Klingons, Romulans, and Jem'Hadar (and I'm taking an atrocity they comit from the Xindi in Enterprise). My biggest issue is...
 * They have their own empire and are very warlike (and will die for honor if they can)
 * They're xenophobic and do not make alliances with anyone permanently
 * Few of the known species know much about them, except that few have encountered them and lived to tell the tale

HOW TO MAKE THEM LOOK?!?

Below are pictures of the aliens I have based them off of, but I wanna know just how humanoid to make them look. Feedback is GREATLY appreciated and begged for here! Thanks and God bless!
