Juuni Hizoku no Palette
Really, really nice story... I think the only thing I think would be better is if it was all full-coloured, I'm sure it would make this an incredibly stunning manga. I kind of feel a bit disturbed though... I don't like thinking that I'm like Theo, but "poker-face" or "serious-looking" usually counts as A LOT of +attractiveness points :P I liked the last two stories that weren't related to this story, The Apple Family and Full-fledged Hook the most. I think that both were good-enough that they could have had their own continuation after the one-shot.
Warau Kanoko-sama
I do love this manga, it would be great to give this to every teenager, maybe they could learn from the "common mistakes" kids make :P I think its biggest flaw is that it got way too episodic, but luckily it's something that got fixed on the sequel :)
Kaichou Wa Maid-sama
Land Of Silver Rain
Even if the art-style wasn't my type, I think it worked well for such a High Fantasy story. I did enjoy the story, even despite the "not as exciting" chapters depicting their lives in the Human World :) I'm really glad that the Great King of Darkness was released from feeding like he had to live in punishment. I liked him a lot. Hope Hanbit found peace for himself as well.
Satsuki No Sora
This seems like it was the pilot for a series that for some reason was never produced. It had a lot of potential, the setting alone had me sold already, there was a big need to go further in depth with what was going on and with the characters themselves. It's a real pity it was just a oneshot, this could have definitely become a favourite, had it been developed properly.
Flowernoid No Shuufukushi
Waaaahh this was such a nice story! I wish there was more, I'd like to see what Sora thought about Satsuki being the same person he helped when she was young. Also about the White Lily flower salesman. I really do wish there was more to read...
Try to Ask Your Heart
Story about a boy that doesn't want to make girls cry, but by doing so, makes girls cry. While I think it's fine if it ends as a oneshot, I don't think it would be bad if the story kept going and it showed harem-kun maturing a bit :P
Birdcage Classroom
Story about birds and relationships. I think that writing even one more chapter would've been enough to make this a really great story; heck even just extending the oneshot to be longer would've helped. As it is, it just started paving the way to a very interesting story, but never really made it there.
