haha, well, basing mission complete on an 11-year old's opinion is one way to do it
This is a big improvement over your previous iterations, but some things that could still use attention:
1 - First and foremost, the face. It appears to be in a completely different style than the pants, which are currently the closest to the PD style...
2 - However, the pants shouldn't use a solid black outline all around. The side toward the light should have a lighter outline! (you did it basically right on the shirt)
3 - Your poke balls look flat, more like hamburgers
4 - The hair is also pretty far off the style.
5 - A few too many fine details on the shirt, see if you can simplify the design some!
This is great progress, just keep it going. Once you've started to get the style a little closer You might want to do something else with the character's left arm, rather than just mirroring his right!
