It would be best to make it as close as possible to the original (i.e., the version from Heroes 7).

Can it be taken from there, or are there no tools yet for opening their archives?

By the way, I found this version; is it from the early artwork?

Replying to everyone: I'll remove the skulls and give him Arantir's shoulder pads. The smoke in the seventh picture was white. The model should be brought closer to the seventh picture, but not excessively. The archives can be opened with the umodel program - this allows you to extract textures and the model, but the model can only be opened in 3DMax with a special plugin. The option above is a fan-made redraw of the human knight.

That's much better!

And which hero will be used for the 6th level?

There are excellent models in NCF format; I don't know what could be changed here, everything is already great.

Excellent models (if only to recolor the glow to match the style).

Fallen Knights. Level 7. Attack 30 Defense 25 Health 200 Damage 25-35 Speed 7 Initiative 12 Abilities: cleaving sword, deadly gaze, curse, large shield, frightening attack, or necromancer - raise dead. Description: not all who undergo the Ashi ritual want to become mages. Some of them become transparent warriors of the Necropolis. These terrifying knights travel the world, destroying everything in their path, and the impact of their weapons is almost always fatal. People, having heard about these knights, are frightened only by their appearance

The left one is too small; it would be better to base it on the Herald, like the other two. And the ones based on the Herald already look like a base model and an upgrade; all that's left is to come up with an alternate upgrade.
P.S.: The Reaper turned out great – I take my hat off to you!

an unupgraded Knight will look like this (or without a helmet, I haven't decided yet).

IMO, of course, but a head with a "bare helmet," without horns, doesn't look very good. IMO, again.

new shoulder pads

It's a bit strange that one of the shoulder pads goes through the shield.

you can give the Knight a round skeleton shield.

a round shield is a good option – then you can emphasize which creature is better protected, and give the unupgraded one the same.

And give a large shield for defensive upgrades.

I made a new, unupgraded shield, and I got that too, but it has some issues with the head:D Nicholas's head started displaying shadows incorrectly after processing, so I'm looking for another donor now (Alaric is next in line).

It seems that the "shadow bacchanalia" is related to the high polygon count of the faces... for now, I'll continue working in the old way.

I've noticed that Duncan's head is often used.
