I've just updated the HeroMachine 3 Alpha with a new "Standard" set for the "Hair" slot, replacing the former "HairMaleStandard". All of the items that used to be in the old one are in the new one too, starting on preview page three, I think it is.
The new set has a total of 71 different hair styles and pieces, hopefully giving you everything you need to customize your character to the tee. Here's a set of twelve to whet your appetite, but by all means check out the live set available now:
Let me know in the comments if there are any styles you were really hoping for that didn't make it, or if there are any changes you'd like to see made. Thanks for all of your earlier suggestions, they were very helpful in putting the group together!
