He looks like a porn star in this one, I don't know about the rest of you guys but I find that pretty funny seeing as that is a popular headcanon for some bizarre reason.
It's a nice picture, but here he looks less like Horus and more like Lorgar...
Lorgar was said to wear eyeliner and had Bronze skin like his father the Emperor(hell some Word Bearers remarked if he grew out his hair he'd look like the Emperor).
