As you can see they seem to be travelling three to a ship, have a brownish green hue and be wearing some type of armor. Their features still can't be made out in any great detail but they certainly don't resemble Skrulls, Kree or any other Alien or inter-dimensional beings I can think of from The Marvel Universe except perhaps
The Badoon (thanks ScarletSpeedster0:), a reptilian alien race older than both the Kree and Skrull who have been known to be "conquerors of worlds". They have no comic affiliation to Loki that I know of but we all know that wouldn't be too much of a stretch for Marvel. What do you guys make of this?
