81 all the way baby. 83 is nice too and more natural, just don't go into flatness that was v0.1... Don't like 81, too thin indeed.
Also some other things... are there going to be varying line thickness in final model? I think this adds a lot more life to drawings.
I think calves' angles should be smoothed a little bit.
Looking back at the v0.2 Krystal, I like her eyes more. Are new eyes wip or finished? They look kinda lifeless to me right now.
Awesome work Katsu, it's really great to see actual progress going on
