Creative indeed! (: You can add in some colours like green, pink, orange, blue or purple to the fonts. Black and white is a little too plain for me. But good codings! Ganbatte kudasai!

Great codings! (: Well, you can try changing the colour of the background, black looks a bit weird. Maybe you can try cream?

This blogskin lacks a bit of colour. Maybe you could have a combination of green/blue/orange with it? The picture can also be enlarged a bit. Overall, neat coding.
