Anime Fuel Community - Characters, Help wanted

I have a few characters in mind for my manga, but im not exactly sure what i want them to look like or how i should draw them, so i came up with this great idea that those of you looking for some drawing ideas or inspiration, you could help me out a bit, by choosing a descrption from below , and post a picture/skecth of how you think it should look . hopefully by the end of this month ill have posted the finished sketches of each one. good luck and have fun, and your art doesnt have to look perfect , it can at least be just a small sketch.

Naomi:The main characters younger sister, around age 14, Kind of short, animated, wears pig-tails, Innocent, a little crazy, loves to flirt, weapon of choice-Mallet

Issac:4th year student at the angel acadamy, tall, smart, oblivious, brutally honest, dresses professional, medium hairstyle, weapon of choice-staff, dagger or bow(the drawer chosses)

ryusuke:Half demon half angel, put into special studies 2nd year student at the angel academy, gothic, strong will, mysterious,wicked hairstyle, by no means is he "special" but very, very dangerous, weapon of choice- particle sythe or demon claw.

Chyuu:magical angelic pet, fits right on the palm of your hand it grows , and eventually turns into a girl which partakes to save the hero of the manga at some crucial points, though theres something that distinguishes it from the rest of the girls, and i cant figure out what.[/

Some set rules as is (if you choose to put)
-Wings(boy) must be on back how ever many , is status or strength
-Wings (girl) are placed on the head and some can be on back, difference is stature and status, never both
-Halo, If acadamy student (required)you can also put it on anything if you feel
-No nude pics , you can come to a style of wear of however else.
-keep it classy sassy and radical :P
