Looks good! Though not all of the lines that need to be fully perpendicular to the horizon are, I feel like that's as a result of some general, understandable sloppiness, than a misunderstanding of the concept. (If there are any doubts, though: that third VP is at infinity (or, close enough to it, that it's safe to treat it as if it is) so those lines are all parallel. Since they're heading straight up, this makes them perpendicular to the horizon.) Anyway, feel free to move on~
