Hi. I'm not a fan of this tattoo theme, but I think a devil silhouette would look interesting. Or you should work well on the sketch with a tattoo artist, and come up with something unique with the face of the devil. This would also look very interesting. But if you do not want to bother with creating a sketch, you can take ready-made vector images. I think devil face you can definitely find in this format.

You can be inspired by various paintings by artists in this style. As for me, to the devil tattoo perfectly fits some chaos around. And just a face or silhouette of the devil is not interesting at all.
