Design a card with your own art! You can use any medium including but not limited to: drawing, painting, sculpture, photography, digital, etc. Make sure to credit yourself as the artist! Try to keep the subject of the art original, don't just photoshop two things together and claim it as your own. Background objects can be pilfered from the public domain.
Please remember: You're not allowed to vote for yourselves. For further information please look at the CotW Rules.
Reviewing each and every card is a thankless effort, though noble. That being said, it could still be helpful if people explained why they voted for who they voted for. Obviously this kills the anonymity factor, but it can turn the contests into something that us less nimble MTG crafters can learn from. Reading the cards that ultimately end up winning is helpful, but this would take it to the next step.
