Besides extra damage shouldn't there be a physical marker of Skyforge Steel?

yes that would be pretty cool

I like the looks. It's in the ancient Nord traditional design, but actually looks new.

Personally I think it would look nice if skyforged steel had a bluish tinge to it, somewhat like orcish has a green tinge. Maybe even a subtle anodized look.

Otherwise, I think a generally nordic aesthetic works fine.

Yes, i agree.

I think it would be cook yo forge skyforge steel and even ebony(even though I think Ebony is elven)

Absolutely. I couldn't believe it when it looked exactly like regular steel weapons
