The only slightly negative opinion I'll voice on the poster is the scale of Starkiller base seems off. The reason the Death Star worked so well on screen was that the superstructure looked legitimate, in that the closer you got to it the more you became aware it was composed of smaller buildings, panels, grid structures ,trenches etc. The issue I have with the SK is that weaponized section of the planet looks altogether wrong, more like a section of a droid photo shopped onto a world. The visibly huge parts used to construct the pieces of it at that scale therefore make it look immediately "fake", which was kind of the problem associated with the original DS concepts. Of course the fact that its on a poster could just be exaggerating this, but its an element that feels very off for me, unlike most of the rest of what we've seen , which hits the button squarely on the head.
