What I learned was that I am not good at lightroom.  I had a hard time remembering what i was support to do, and that it toke me a long time to get it right.  I learned that when you do remember it and start it, you can get it done really fast, when you know what you want to do.
what I did was find the best or funnest pictures i could, and then from there I just moved colors and highlights.  i tried to find the best way to make it ugly, but what i found it the more i tried what the cooler they got! weird I know.
