I think you need to aim inbetween bengoshia's and BG's edits, It does have some readability issues, which isn't that hard to solve if you just try think in terms of contrast and which colours work well together. you shouldn't overcomplicate it by putting too much detailing in to only a small area, this is what BG's edit suffers, though he has been brave upping the contrast here and there and simplifying parts trying to cram in more has made it harder to read. Imo the character just looks shes had a new hairstyle and put on a bit of weight, because not much has changed with it's readability.
bengoshia looks like he's taken his own take on this, which possibly strays too far from what HTD was trying to accomplish. I disagree you have to put the detail to a minimum, I'd think of what details are essential because otherwise these characters would just be made up of various simplified shapes.
I've possibly strayed away from the style slightly but I agree your characters look a bit stiff HTD, loosen up a bit.
Also I tried altering the angle to make more sense to an RPG. Not sure about the hair though, oh well its only a suggestion. Hope this helps atall mate.
