The thumb is covered up by the pokeball.
Your drawing is drawn from direct, in-front perspective, where since the hand is shown directly palm-open and frontal like that, you should be able to see the thumb naturally resting on the side of the Pokeball. =P
I would have defended you saying that you don't deserve all this harassment and flaming.You've run out of insults. Just give up, like god has on you already.
But,
you posted mediocre artwork deliberately outside of the Artwork forum, simply because you thought it was "Brawl" related, and you HONESTLY expected you were going to get positive reactions out of people.
Sorry.
