You're right, man, this is absolutely epic! It's just a pity how you did such an awesome coloring job on lined paper. It ain't super annoying, of course, but a little photoshopping might do the trick ;]
Like DoRaiMeViVi said, simply amazing and I see nothing wrong with the pink and blue rubbin. I feel that it adds more color to the background and I love how you blended to ribbon to change from pink to blue.
