Ideas for drawing Fingolfin vs. Morgoth

[Beregond]

And now for something completely different:

I've gotten into pencil art the last couple years. One scene I really want to draw is the tragic, heroic duel between Morgoth and Fingolfin. It's been done before by such amazing artists as John Howe and Ted Nasmith, but it's such a powerful story and l want to draw it myself. I don't want to copy their visions; however, they drew the scene much as I had pictured it when reading the book, so I can't make it too different.

I have a picture in mind of what I want my drawing to look like, but thought it would be fun to ask ye knowledgeable folk for ideas. What kind of armour did the combatants wear? What did Grond look like? Is there anything that bothers you about previous artistic renderings of the battle?

I'd love suggestions.
