Lovely! I really like Peorth's design. I'd say her and Belldandy's are my fav designs from the show. I've just started to watch Ah My goddess, well actually I've seen a bit before, but it was like the 5th ova, haha not the best bit to start the series I know, but that was ages ago XP
Yes, I think you are quite good with your drawing of roses too :D I think if they were a bit more bolder in color, it would make this picture stand out more, but otherwise I quite like the tones you have used for Peorth.
