Aw, he looks adorable! I love the kitty-ish ears. The lines looking like he's 'communicating' with them are a very nice touch--they go nicely with his blank expression, like he's having trouble understanding what someone is saying to him.
This is definetly not a failed attempt. You started coloring, which is a great start! Your lines are much nicer than a lot of colored pencil users--they are all going the same direction, though I have to say colored pencils are tough to use for the cel-shading technique that is used in most anime pictures. The colors themselves are very nice, and I love the background lines. The only thing you're missing on is shading. Shading takes a long time to get a good hang of--shading doesn't just mean darkening areas, you need to add white or light highlights too. :) So try that with your next pic--look at other art for reference. And good luck!
Oh wow thats good. Looks a lot like him. I saw that episode. I don't think its a failed attempt at prismacolor, its a good coloring job I think. I like the expression on his face ^__^ it fits.
