How cute! I agree, I think color would add alot to this piece, and make it easier to differentiate between the characters as well. Good work with the lineart, though next time you might try to vary the width of your outlines for an even more dynamic picture. Good job! ^_~

I love it...It looks good. Add a little color and then It would be great.

Really good. though hikaru's hand should be a bit smaller....
