There isn't actually that much to forget about what happened with the girls in the original timeline as the information about that is quite sparse in the game and most of that you got about right. Non of the main girls had a awfully fulfilling live though. Alyvia got it somewhat together after her first marriage but she remained scarred, Emily handled herself probably the best of all the girls but she grew very distant with everything from her past, Jacky pretty lonely and most of the time drunk, Cathrine very successful but childless and kind of bitter. Stephanie and Viktoria probably got it the worst.
About Leo I actually haven't thought that much. I think he did alright though.
Not completly sure what you mean, but I think I'm a bit more generous with the bloom then other hs2 devs which makes everything a bit more glowy.
I actually wanted to tone it down a bit from v0.7, but its kind of like when I get my hands on a boob slider, really hard to control myself.
