I understand! Merlin's face is quite unique, what with those poppin' cheekbones. I've only seen one Sim creation of him and it didn't really do him justice. *I think* he's really beautiful looking but trying to capture that must be difficult!
But then, he can go from being really ethereal looking in the show to suddenly like a huge, awkward goof...But still cute, if you ask me!
You did such a great job with Arthur, if anyone can make Merlin, you can

Ha, no pressure...But if you ever do make one, I'll be sure to download.
