Phoenix airport

If you can't tell, I'm really trying to post a lot more lately to keep myself working on different things. That's why I'm trying to work with color and textures in more recent pictures, which I'll try to post more of soon. I'm somewhat new to textures these days, so if this is too much, let me know! This one was when I was waiting for a plane in the Phoenix airport for 3 hours, because of inclement weather in Denver. Seems like every time I travel I get stuck somewhere, but I'm getting used to pulling out my sketchbook at these times, and kind of starting to enjoy this forced people-drawing time.
