I can see why Cleopsis is a favorite with all her detail but for me personally it's easily my least favorite. The whole Egyptian theme really feels out of place when compared to everything else. Perhaps her soul is a 1000 year old mummy but eh. The detail is impressive but it also makes the whole thing very busy on the eyes. I've always found beauty in simplicity so it's no surprise to me that I like Queen more. It always seems harder to make something great that is also simple/subtle like Darth Talon PF. Cleopsis lacks subtly in general while Queen is very disarming but just as deadly.
The Siren is 50/50 for me. The top part of her is great while clearly pretty there are subtle warnings that she is definitely not human or nice. Her lower half i find a bit obnoxious with the men still clinging to her tail, shows off past kills perhaps. I don't think they were necessary to make her feel deadly her grotesque fins was more then enough for me.
For this line I have Queen and Kier on pre-order. I'm mulling over Death as well not sure yet how much I want him.
