To be honest, when I spontaneously think of Loki, something else entirely comes to mind, but that's since I got the Norse version first, long before I could read and Marvel started to come my way (and even then there was another comics series, the Danish Valhalla, that shaped my view on the looks of these people). He definitely doesn't have horns in those. Nor a spangly outfit. And I grew up with a redhead Thor, BTW.
The outfit looks a lot like the one he had in Thor, when they went to Jotunheim, aside from those vambraces.
