Melkor's depiction by artists: Flawed?

[Kuruharan]

I think Morgoth's other servants had a terrible air about them because he was deliberately trying to make them degraded and vulgar.

Of course, maybe that means that he made himself look that way too.

I'm always in two minds about Nasmith's artwork. Some of it I find utterly inspired and some of it I find rather lacking.

In my opinion it is his landscapes that are amazing and his figures that are underwhelming. However, his figure work has improved in recent years.
