The monster silhouette looks kind of cute.

Nice icon, maybe you could have added more reflections on silhouette to define the depth, therefore giving it somewhat different shape.
For your future icons, for works with detailed compositions we usually ask authors to attach big images to first post or in the description.
The title should describe the icon, so you can add ''3_wc3: Dark Ritual'' or something like that.

[+] Nice color pallete, love it.
