What's weird to me is that bottom tier is far better, in both posing and relation to the ground, than the whole first page. Sue seems really awkward up there, and seems to be floating slightly on the ramp, as opposed to the bottom where she's relaxed and on the ground.
Same way the kids look much better on the bike than they do in the room together, and Johnny doesn't look good at all. There are a couple of panels where even for a kid Val's head looks too big, but it's sort of a fine line to walk so it's forgivable.
