Mastermind vs. Mastermight
Exploring your own creations is always a good idea, and it helps to broaden the perspective of the concept. This is a really nice art style and the characters are well drawn, and the coloring and the shading are of course well done without objection for the chosen art style. By the looks of it "Femme Fatality" does her name justice and suits well into the MM concept but the Mastermind himself is quite comically portrayed.
I really enjoy the art and animation style that you already have in the Mastermind series. This Mastermind version conveys a "more brawns than brains" presence and his gigantic hands could probably break rocks and squeeze skulls like bad fruit while frightening everyone around him with that insane expression that gives the impression of that the guy's mentally unstable and can freak out any moment, and that is kind of taking away that unique charisma the original has, but this version is more humorous instead.
The original Mastermind is intimidating through the look of his well built body, his calm and calculating facial expression that hints of an evil genius, and with his dark and commanding voice you really get impressed with the guy, and when it comes down to business he's nothing but an egocentric idiot and only sits there in his chair while bullying his own underlings for amusement, and still he has an army of loyal soldiers that follows him, and sometimes I wonder if he is just eccentric and bored. This is what I believe that makes the series so damn amusing and special.
It is a nice doodle nonetheless!
