Pretty cute
As usual, you know how to capture the essence of a character's cuteness. The best part is how he is just standing there looking so silly. Probably the only thing I did not like was how it didn't seem as well detailed as some of your other works. I guess it's because he lacks a mouth, but he does that automatically anyway. It's pretty cute to envision him with the little gun and sword. Well, at that size it's not even a sword, probably a knife.
I like how he seems to have these little boots on. I'm not that familiar with the comic book design, but that's probably from the comics. I would think most cards would have the character's name printed on it. I just now noticed your signature in the bottom right hand corner. It makes sense such an awesome guy would be one of your favorite characters.
