Scarlet Steels, this doesn't sound right nor does it abbreviate well, "the SS come to save the day!". This is really a bad carbon copy of Power puff girls, Tom boy✓ Leader✓ Cutesy Child✓ . Then you have the Professor✓ which has the body of a kid yet the VA of a man which doesn't seem to fit right. You have a city in peril✓ and viola it's the same thing just skinned differently. Toss in the mature rating and it can only spell creepy. Futurama was right about humanity and it's down fall with love interest in the robot / androids "I dated a robot, via 2001".
You do however have a good art style and that is something to build from. You have good VA, just not placed right. That's about it, two good things. I think you would've done better to have had three girls make or find the suits or a lost military bunker and they become city heroines. While meeting an old bunker general that doesn't know what year it is and believes some old war end of days is still happening and helps the girls fight them. As for a better title name it's really tough when you're borderline copying from other genres out there. Let's face it, it's all been done before but it isn't a lost cause as there is always a way to deviate without looking like a carbon copy. I don't know "Heavy Caviler Three-HCT" "Raiser's Edge Three-RET" "Dawn of Blade-DOB" "Babes and BadAss Suits - BABS" really I'm just tossing ideas out. The SS just doesn't sound right if you know where I'm going with it.
As it stands right now it was very cringe worthy, forced jokes and weird sexual tensions that didn't fit right. But I doubt any of this will change your plans and you'll keep on with this as you've stated in prior posts you have episode two coming out soon.
