Certains persons say you mustn't do too many details.
Personnally, more there are details, better it is !
So, you pay a woman to draw the line of the characters, the you colorize those linearts ?
And about Shir, Phantasy Star 2 is the (classic) PS I less know, but a thief dressing like anybody seems me fitting the side "nobody knows i'm a thief" ! But I like her new design, effectively more thievery. If I have to draw her som day, I'll probably let her ancient design, with extra details... as I'm used to do !
