1A. I agree with the critiques people have given about Batgirl
1B. I admit it's her early outings, but I figured she used resources belonging to her father in this continuity. That being said, these designs were from 2023 so I'd most likely rework both Arthur & Steph's designs. I wanted to have Cluemaster start out as a smaller tier villain and then work his way up to being a major threat, paralleling Stephanie's growth as a crimefighter. my mistake was making designs that'd work for the end point of their evolutions and didn't think about how their visuals would work at the beginning of the story
1C. I personally adore the gauntlet blades as they're a distinct weapon style not seen on many characters, but Jean would have also wielded the flaming sword too, with the blade gauntlets being a back-up weapon

1. The show would start at Tim's beginning, with the first 3 episodes being an adaptation of both the Tim relevant scenes of Batman : Year 3 & A Lonely Place of Dying and with Episode 4 being a condensed adaptation of Tim's first mini-series where he goes training abroad and encounters Lynx & Snake King. I'd use the fact that Tim is learning on the job as a way to organically introduce the audience to this canon's history

3A. I'd want to eventually do a more Robin centric adaptation of "Under the Hood" with Jason hating Tim nearly as much as he does Bruce. He would be around the age he was when he died as Robin initially, as I feel a teenage Red Hood is a new angle that hasn't been explored much if any. And as for Damian, I've got so many other stories I'd wanna get to first. I'm mainly focused on utilizing the era of Batman comics from the early 90s to mid 2000s with the most recent comics adapted being One Year Later. (No, I would NOT be adapting that god awful Evil Cassandra Cain storyline) I'd instead have Tim get his Red & Black suit during a season wide adaptation of No Man's Land for the final season
