His eyes...

Right now in my creative writing class, we're learning how to use tone and description without using things like "They were so pretty" or "I ran as fast as I could." So I'm posting this little bit here as practice. Tell me what you think ^^

I glanced up from down on the floor and gasped at the sight of his eyes. They were like baby-blue diamonds. Even in the dimly lit halls of the old run down school, they still shown and sparkled like we were standing in the middle of a summer day with the sun shining directly into them. His gaze made me feel hot as I felt the rush of blood spread to my face. I knew I was blushing. I was probably blushing harder than ever before; I was sure I looked like a cherry. His eyes stayed glued to mine though. I wanted to look away but it seemed like they were playing the song of the Sirens, luring me closer and closer.
