I have played those levels you've mentioned and while the intention is good the execution isn't so great. As for me, I suppose you could say I'm very detail orientated. It is killing me so much not having the theme in my level, but hopefully someone can come along and give me a hand with that.
Anyways, if you log in to http://www.lbp.me
with your PSN account and go to http://lbp.me/v/xfwq8b
(it's a shortened URL to my level) click the green Add to Queue button and the next time you play LBP2 if you enter the Community Levels section it will now be added to your queue for you to play.
