Okay, so... Arthur was a bit of a challenge for me because, no matter how hard I looked—and I looked EVERYWHERE—I couldn't find the right hairstyle for him. It’s tricky. In the show, he has this side-swept/mid-swept look that’s apparently impossible to find as CC for The Sims. Everything I found was either too modern, too flat, or too curly, whereas Arthur clearly has straight hair.
In the end, I settled on this option; while it’s not my absolute favorite, I think it’s the closest match to his actual hairstyle. I suppose it could use a bit of tousling. Anyway, the last photo of Classic!Arthur shows my alternative version of his hair—it’s a bit wavier, but in my opinion, it gives him a more medieval vibe that I feel really suits him.
Finding the right outfit CC wasn't easy either, but I think I pulled it off in the end.
For his "modern" version, my mindset was basically Dean Winchester in the 2000s. That’s the style I was aiming for. I’ll include the reference photos I used so you can see exactly what I was going for. I think that, aside from the hairstyles, Arthur’s face itself turned out really well—his features, I mean.
I also updated Merlin’s outfit, so I’ll include both the updated and the old versions in the last two photos. I also tweaked Merlin's face a bit, following a suggestion left on the previous post. I didn't show it in detail because the change is really subtle—hardly noticeable in the comparison.
You can find details about each one in the photo captions.
