How/when do I enter?

Is it too late to enter? I would wanna enter in drawing, or, to be もっと見る specific, マンガ drawing.

Just for fun, I drew the following picture. Would あなた think I would have a chance? Any suggestions?

And, can I enter in someone else that's not me?

If あなた answer, and I'm bored/nice enough, I will give あなた props.
