I think the blessed ring was already in malevolent and Benign, but thank you nonetheless, as it shows good taste in your monstering. :)
I didn't even know about that until now. Looking at it, it's literally a straight up conversion from the 3.5 version, and all they did was add the Natural Armor feat twice. They also lowered the Con by 2, but increased the HD by 1. This lowers a couple of the DCs, but they left the Ability Focus. Not only that, it has no Str and Dex still. By the stipulated Monster Creation Rules, this creature is not on par with the standard creatures.
I can't say I like mine best because I'm sure someone would find flaws in it (for instance you don't actually need detect alignment because of it's soul sense), but still.
As I pointed out to Sean K. Reynolds earlier today in an email, his RPG Design Classes should be mandatory. Especially for anyone wanting to convert or make their own creatures.
Thanks for pointing that out. It's appreciated. I wouldn't have known otherwise.
