Why is your character smiling? Please state your reason. and, uh, those kanji symbols mean....

Because he just did something naughty. But I haven't quite decided what yet. Did you watch the new "Nabari"?

I like this one.
I think you are good at coloring with color pencils.
I cannot do that, that's why I color it in photoshop instead.

I know "HITO" means human or a man.
But about the other one I have no clue.
I've never seen this kanji before.
These two letters have something to do with the "mischief" title?
Maybe I can guess "KEN" easier.

Thank you so much. That means a lot to hear you say that because I just started coloring with colored pencils about 2 months ago.

As for the kanji, I'm not sure if its right, but I was searching around and I think the top one means "mischevious" or "evil", and so that would make it "mischevious person". I don't really know. I studied japanese for a while but I didn't learn all that much kanji, so whenever I use it I just end up guessing!

With Pleasure, friend!

About Japanese, I think this word can be suitable for this pic's title.

AKUJIN あくじん　悪神　means an evil god, or the god of evil.
Aku means bad, evil and mischievious. Jin means a god.

You can also use AKUNIN 悪人　あくにん　which means a villian.

I guess you may know this word "Warui わるい　悪い." It means bad.
Actually you can use 悪い人　Warui Hito = a bad guy...but I think
The Villian > The Bad Guy...it is more powerful, I think.

I'm not really sure that the first kanji you used as a title is Ok or not.
As I told you I've never seen it before.
I learnt Japanese for 5 years, but you know, I'm not Japanese...so these words are what I can think of!
