Answer from Dark Horse on fb:
Thanks for your inquiry! Due to the huge pool awesome of entries, we are still determining our winners. Stay tuned for more news soon.
Good to know, though not really surprised. There were a lot of amazing entries - and a lot of fraudulent entries they are going to have to sift through (even had two of my older art pieces submitted by unknown people as their own). Anyways, hopefully we hear news soon.
wait.. the contest should be closed but I noticed that we can submit?
Thought they had removed the locations you could submit at, but regardless, I'm sure they wouldn't be valid as they'd see the timestamp of when they were added.
