This is a model I started a long time ago. Never got around to finishing it, but I think it's good enough to post. I used 3D studio max and Zbrush to make it.
Better than anything I could currently do in 3D. But I will say this: My only critique would be that if you were to redo this, try to make the horns look more attached to the head. It looks like you raised the head so that the horns would fit, instead of designing the head naturally and making the horns fit accordingly. Other than that... 4.8/5
