I like how you took an actual picture of you monitor. lol
To make things more clear and more professional, use Print Screen. Just hit Print Scrn, open up your favorite photo editing software, paste, then crop away what you don't want.
As for the coaster, I'm diggin' the layout. Parts of it look very broad, which leads me to believe some of the turns are weak, but maybe I'm wrong. One thing about the AHG, use smaller segments. I'd shoot for segments around two meters long. This will make the shaping of the track after AHG more precise.
Good looking coaster. And welcome to the site.
