I get what you're saying about the odd colour saturation with the XP RTP. The shadows look really odd to me, too.
As to what Holk was saying, I see your point about eye-catching, but I'm wondering exactly how much of it has to be original content for you to consider looking. For me, it's actually pretty low; I'm easily taken in by decent promo art and a well-done title screen. A few original facesets/battlers would be nice, too.
You think more people would make their own facesets or get someone to do it for them, but usually it's Kaduki (which looks okay, but as I said earlier, the male faces look kind of odd) or some facemaker garbage.
I am actually biased against the facemaker app to the point of near-condemnation. I can't really stress enough that the art bugs me and that it's super-ugly.
