I decided to choose the characters for this poll based on their colors. I'm asking the question of which one seems to represent springtime. I also chose a few background and side characters that don't seem to have many or any diaper art. I'm thinking of keeping this poll open until Saturday.

I realized I forgot to post this sorry about that. I thought had clicked post on FA after posting it on Deviantart. Edit: I'm leaving it open until Sunday.

Edit 2: I'm closing the poll at around 5 PM CST.
