Number 30 is your own artwork. You shouln't vote for yourself as the rule say:
Participants cannot vote for their own submissions, but they will receive an extra 3 points for taking part in the voting. If a participant submits multiple posts, the bonus points will be added to the submission with the highest number of points. In case of a tie, the points will be assigned to his first published post.
Vote for different artist and you will get your bonus :)
I have updated my post Boss
