Monster ossociation excetutives

Hello all I want to show you a sneak preview of my later will have the monster excetutives that will face our heroes and they will have to proove themselves and their justice culture to the monsters. I think my drawing is better then my story writing so, but is not also so good, but I hope you like. Each is based to fight one hero and to fight their strengths.
Also Elder centipede and Homeless emperer will fight them and more later. Is just preview. I hope you like! Tell me how is it!
