Oh! It's all colored pencil. The smoother parts are where I pressed down really hard or went over it with a white pencil (There's a fancy name for that technique but I've forgotten it). Thank you though!
I believe it's a technique called 'burnishing'. My older sisters tried to teach me once, but I have since forgotten their lessons. It is great for blending, though. Looks real good the way you did it. ^^
(Sorry to butt in there, but the name came to me in a flash of light, and I had to share. I'll be going now
)
