Hi @riponr your drawing is very nice but Splinterlands can't vote for it.
You can receive a maximum of two votes from the @steemmonsters account within 7 days.
Next time check if you have already received two votes in the previous 7 days, those who participate more than once in the space of 7 days may be put on the list of accounts not to vote.
It's not your case because it's the first time it happens but follow my advice ;)
