Houston Bush has a rather bizarre layout. There’s very little consistency between terminals, yet it somehow still comes out as aesthetically pleasing when it’s all put together in a single silhouette.
IAH also had the same issue as Phoenix (PHX) where parking structures are built over the top of terminals. Normally I wouldn’t include parking in a terminal silhouette, but as with PHX I opted to include them here since they’re such an integral part of the terminal layout.
I recorded a time lapse video while I was creating IAH to show my drawing process:
