I think Loren's artist is the ULTIMATE artist!
He was able to draw everything well: male/females, monsters, sexy stuff (obviously) but also armors/items, etc. Really a notch above everything else. But he was unable to color anything (that's why the coloring styles is different in several games with his art).
Rebecca (this artist) is of course very good, though since her style is not "pure manga", some people don't like it. She colors REALLY well, the CGs of this game use an even better coloring/shading, and she draws body proportions very well.
Downsides - she doesn't draw nudity or anything too hot.
Like for everything, finding the perfect thing is hard and more often than not I have to make compromises. For example, I think also Queen Of Thieves artist is great, but is super busy so for him doing the art for a game takes 1 year minimum (if not more...).
Another artist who is good I think is Undead Lily artist (the one who also redid PSCD art, though I prefer the UL style).
