Did ever happen to you that you started a drawing, yet somehow ended doing like six sketches at the same time?
Yes. Though given that back when I was a tryhard novel writer it was perfectly normal for me to have at least 2-3 things on the go, it was only natural that this continued when I transitioned into animation becoming a studio because I'm an idiot!. Doing several things at once as a studio is slightly harder than writing or drawing several things at once though XD
Anyway the moral of that was it's perfectly normal (whether or not it's "good" or "bad" depends on how you feel about it and how it's affecting other things you're doing).
Nothing wrong with having multiple styles (I have three XD), consistency does speed up your drawing though, maybe that's why you've got so many on the go now :D
Ahh this one is one of those is she XD Do your characters have interacting storylines? (sorry you've probably explained this before and I'm just derp)
Saeko is... special, but you can't honestly blame her once you get to know her story.
As for the interacting storylines thing, some do while others don't. It's not something I explained before, don't worry xD
Shayla & Evelyn have interacting storylines. However, they have nothing to do with Hakuno and Saeko.
Hakuno herself is an OC made for a fanfiction, lol. Started off just as the MC's new identity, but things... scalated. Fast.
Then there's Saeko, whose origins are unnecesarily complicated. Long-story short: my friends and I started a new roleplay game, only the GM was like 'let's make this a crazy trip across the multiverse' and we went W I L D.
The only thing I was worried about was having been told something before but forgetting (because my memory is weird), so yay XD
I totally understand about things escalating fast XD I originally got onto my current batch of characters by redrawing some fan characters as humans (and then realising one of them was missing parts and adding wings, horns and tail to him "for no apparent reason" as I described it at the time but the real reason is I just have to do whatever these things tell me to XD) because an old friend told me that they were "too cool to be fan characters" after reading a scene I'd thrown in a forum for critique.
We all start somewhere(?) Also "too cool to be fan character" what an iconic line xDDDDD
