SuperMarioWorld-Reproduction

This is a reproduction of a low quality jpeg of a screencap from the Super Mario World cartoon intro. I had to make a few changes, but it's more or less the same. I love that shot and that intro. It's just so cute, and I like how Mario, Luigi, and Yoshi are drawn in that style the best. I have the intro on my comp, and I'd been meaning to redraw that shot for at least a couple of years, even though I didn't get to it until yesterday. I also have a wallpaper version, my current desktop.
Lines - Illustrator
Colors - Photoshop
Original image by the animators and background artists, I guess

Why couldn't the actual show look that good?
