I like the overall theme (sexy succubus, right?), however, something about the head seems...off. I think it's the hair; not voluminous enough? I also like how you used the Carol as I don't see it used much.
I like the simplicity of the avatar and how you used well the heels of Rosamund Redemption, just what disturbs is the lack of blue on the bottom. In this case, use the "Heavenly Blue Unmentionables (Blue Stockings)" that will compensate the lack of blue.
I'm a sucker for fantasy, warrior-like avi's. I'm not sure if it's a direct cosplay but it's really cool & the colors are consistent all throughout the avi- the background just makes it more obvious of the theme. 10/10
A bit of a mess for my liking, I can't really see the theme and the items don't work too well togheter. My advice is to find some kind of flow with the items, the colors are nice but I would use more tones and follow perhaps a scale of dark to light or viceversa. 5/10
