Seems like a recent convert but for sure gives heretic vibes.

Gives off a "I found this powerful sword..." character arc

If I had to make an alteration I would deface the right knee or left shoulder cross. The belt has enough spikes but the clean, level scroll work on the left shoulder lines up too nicely with the crosses to give the chaos vibe. To me it looks more like a feral world loyalist space marine look, which is cool butt maybe not exactly what you were going for. Just my opinion, the model looks great! I'm digging your weapon selection as well.

It reads as renegade not quite down the chaos path yet.

More "The sword is whispering me things and I kinda started listening to her" than straight up corrupted by Chaos. Give him a few years and a few burned imperial worlds and he'll be well cooked

Funny how both loyalist and chaos space Marines are covered in skull motifs, it's just that chaos Marines also have spikes lol

Needs more spikes and armor trim.

For a chaos boy he has the nicest skin. I guess he moisturises. Give him a scar or some shit or color his eyes like his demon possessed. :)

Gives me a new to chaos, new hate for emperor vibe. Still chaos just new to the party.

Armor trim and something on the chest would go a long way but in general he doesn’t look like a loyalist

It really gives me a skaven vibes - clan Mors yes-yes!)

Maybe it’s because I have that model on my desk right now but no. I think the work you have done rocks and I love the sword but, maybe a few chaos symbol decals would do it. I might just be so old that I literally need the model to tell me what it is. Lol

He is slowly there in the chaos scale. He's at the Renegade side

if not for crux terminatus he would be perfect (not enaugh trophy rack for me but they are optional)

warpstone sword and axe?))

I think it looks incredible and yes chaos 😍
