This goes for both of your latest "creature"-icons;
Sure they are nice icons, but what usefullness do they have? I can tell right now that probably no one at all will use this anytime. As long as there is no model for an icon like this there is no use for it.
The icon-section here at the Hive is a place for people to find icons they need for their projects, not a place for you to show off your artwork. Use the 2D-art forum for that. There is no need for you to make icons of every character you create.
You need to think more before you deem something as useless. This has good quality and looks very neat. If not used with a corresponding unit model, it can be used as an icon for abilities, items, or buffs.
This icon looks great, 5/5.
Edit: Since Elainiel insists on ignoring other possible uses for the icon, stubbornly pretending to be right, I'll directly state a few examples of possible uses for this icon:
An item such as a mask
An ability, with the icon representing the face of an evil god which you draw power from
An ability for a wolf using an evil powerup ability (which, when casting, would attach tusks to the wolf, causing it to fit the icon perfectly)
That's three uses right off the top of my head. Do not constantly smash someone's resource just because you are too slow to think of any use.
In my honest opinion, I would give this icon a 5/5 in terms of how it looks, a 5/5 in terms of how well it fits with other Warcraft III icons, and a 3/5 in terms of usefulness.
Something does not need to have 9001 uses to be accepted on hive. In fact, if this icon was created specifically for a model, as you claimed it should, it would have only one use in correspondence with that model.
