Yeah, heights are always a problem. I suppose they do line up good enough for display. Personally, I like to try and get them all as close as possible to their on-screen height... with the exception of ones like Tyrion.
This guy just arrived, photo straight out of the box and I have to say for the price, this is very, very impressive. Likeness is spot on and the body proportions aren’t nearly as bad as I feared. I don’t need two Khal Drogos so this will do for me even if TZ eventually release their’s.
