Okay, the problem isn't necessarily with the character ideas.

The problem is that you're obviously [i]really[/i] new to this and the writing standard simply doesn't match up with what's expected. Writing on a mobile or not, your posts are completely lacking in proper punctuation. In none of your posts so far have you used a single full stop to end a sentence.

Additionally, with a bio that brief, it's extremely doubtful that any in character posts you make would really be long enough for casual. If you want to make bullet-point style bios without punctuation, you'd be better off joining roleplays in free.
