Plane Spotting around IAH Airport

So had a quick weekend trip but some long layovers in IAH (Houston International Airport, Houston, Texas). So decided to walk all the terminals and check out all the planes that are stationed there for that time. I found a bunch of cool ones and ones I really want to fly in the future. The most amazing one? The Lufthansa A380. WOW.

Flight Views from LIT to IAH. Clouds looked really rad.
Coming in for a land, looks like landing in Ireland or something, nope just Texas.

Spending time at airports your like why cant I identify these planes, so I had to learn. Youtube as well as some guides they sell at airports are really helpful.
