for the scoreboard I first found one of some other game. It had two other college names on it, so I took copies of each individual letter and tried to form USC/Nebraska. I was missing some letters and had to create a few from scratch. I did this by copying one of the individual lights and blending it in to form a new letter. I did the same thing for the score (the original read only 9-14).
Then I just worked on making it look like a reflection by warping it and blending it in...and then added a sky.
The real fun part was the Trojan logo as I drew that one from scratch to help it blend in better.
