I agree with Fanpup as an icon, but I think あなた should change it [image file, not Fanpup]. What I mean is that あなた should use image of a better quality, without any words on it. They're all uploaded to this spot. Thanks to this アイコン will be もっと見る 'clear' because now it's not that much clear, it's a bit blurred.
Here's the link to it:
link Don't worry that it's too big,Fanpop will automtically resize it, and thanks to this it will be better quality. I added it here, it's PNG file that's why it has black background. But if あなた use this as an アイコン ファンポップ won't add the black background, this happens only on フォーラム and answers, but not in アイコン または picks.
I hope I helped.
