I'm going to tell you this right now, I don't know your professor but I can almost guarantee that if you keep that gradient on there he will not be happy. Stick with bold shapes in black and white until you've worked out all the details. Then, and only then should you start considering colors or gradients and highlights, etc. (NOTE: most logos do not need extra effects like web 2.0 highlights, gradients and drop shadows and they generally should be avoided unless you have a specific and meaningful purpose for using them.)
