I wouldn't go so far as to say I'm "glad" she's gone; the work she did for Harmony of Despair was quite nice. Her manga work is also well-drawn (The SotN prologue, did anyone actually hate that artwork? I don't think so). However, I like the fact that there's a variety of artists working on Castlevania, if we had Kojima for every game then I would be sick of it. But she hasn't, there's been Masaki for OoE who I'd love to see return, the art for CotM was nice & appropriate (especially the box-art), even the art for Akumajo Dracula The Arcade was cool. And I'm on record saying the artist(s) for the LoS series are excellent as well.
If anyone has bought her artbook Santa Lilio Sangre, then you'd realize that she's more than capable of drawing a wide range of styles; not all her men are "girly-looking," a common criticism I see from most people. I wish she would have done the art for The Belmont Legacy comics, as I'm not really a fan of that artstyle, it's too "generic." But yeah, even though she's on a hiatus from the series, I'd love to see her designs for a future game, perhaps the 1999 game, or even a game based on Bram Stoker's Dracula should they ever make one (her Victorian designs would work perfectly for the setting, imo)
