Well, I've always wanted to be on a first page, so I'm going to edit this post into my real answer.
Anyway...
My favourite April MC would have to be the Voracious Fog. I like this item because of its multiple poses, its eerie theme, and its foggy badness. Sure, it doesn't go with my avatar in the slightest, but it still looks very nice, and it obviously had quite a work put into it.
Plus how could you not love the Heart Costume pose? Evil Fog emanating from the blackness of your heart is pretty amazing.
Yeah.
