Hero replacer.

Grol looks almost the same in the artwork, and Marbas is also muscular, just leaner. Let's say that after becoming a demon, he's now bulking up. Agility isn't that important anymore with hooves (an old joke about why Draenei and Tauren can't be rogues - their hooves clatter too loudly).

Nebiros and Vayre look very similar. A quote from the fandom: "Jezebeth initially had a slightly brighter texture; I think it would be better to darken it a bit" (damn, I wanted to share the original file with separate layers for her body and armor, but I think I accidentally overwrote it).

In the artwork, Nimues has even more horns, but my ability to add them is limited. Although, if I remove the last two pairs from the archive, it also looks pretty good, but it's not lore-accurate. By the way, in a way, because of Nimues, I put the mod on hold for half a year; I couldn't create a decent armor for him. I'm not a very good artist. Although, I probably just got tired, and Nimues was just the trigger. Although the other five heroes were ready last year.

I think Grok already looks very similar, except that his horns are lighter and his armor is red. I didn't want to recolor the armor, and the horns are a different story - I didn't clean them like I would brush my teeth in the morning, so they got sooty during the day.

In my opinion, the demonesses turned out well. This is probably the maximum that can be done manually in such an old game. Unless, as I mentioned, the color of Jezebeth might need to be adjusted. By the way, why does Jezebeth have yellow eyes instead of red? Was that the intention?
And if we're being really picky, it's unclear how lifeless Daleb's face will look in the game. In the artwork, it's as lifeless as possible. But that sometimes happens when the artwork looks worse in a static image than in motion. So, I didn't dwell on it.

Wow, I've never seen the concept art for Grol. HE'S SIMPLY AWESOME! It makes me want to play as him.

Well, Marbas could very well be your own interpretation, why not? But I think a more "Agraal-style" look might suit him better. He's just too massive. But that's just a minor quibble in the context of such great work.

Is there any difference from Vayre?

Well, maybe darkening Jezebeth's texture is a good idea. Perhaps that's how she looks better in the game. We didn't see the previous version, after all. I just noticed the discrepancy with the concept.

Indeed, Nimues is a horned devil =D. Thank you for coming back and doing it. It's very timely, because I was just wondering if the Inferno heroes would be released yesterday, and here's the announcement =D.

Well, I think the hair on Grok differs from the artwork. In the mod, it's more purplish. Although, it should be bluish/black?
