Design- Character Design

There is a collaborative nature in the realm of art forms that tell a narrative such as film/tv/graphic novels.  Before stories can be told, strong character designs must be in place to define each character.  Often one creator creates concepts for characters and another takes that written information and translates it into a visual.  It is essential that this collaboration is done with clarity and accuracy so key elements of these characters read clearly to the viewers.  
Below are three descriptions of characters who already exist in some form.  Your objective is to choose one and create a visually pleasing design that effectively describes who these characters are.  You will begin with a series of thumbnail sketches to work out at least 3 DIFFERENT approaches to presenting this character.  The most effective one will be developed into a full color version on 9 x 12 paper with any media you choose.

1  Female character with a streamlined, aerodynamic costume built for enduring high speeds.
She wears a collared jacket and heavy duty, futuristic sneakers, and bright runner pants with a color gradation of some kind.
She has armor on her forearms that could be used as weapons or to house objects/weapons.
There is a glowing energy device strapped to the center of her chest.
She carries twin blasters.

2  Floating male green creature with no legs and long skinny arms.
When he speaks, he has a special font to represent his speech/language.
His eyes are very pronounced.
The texture of his skin becomes bumpy towards the top of his head.
He has a letterform on his belly

3  Tall creature walking on four extremely long legs with stilt-like hooves, no clear gender.
On the shoulders of the two front legs are what appear to be large ears.
The head has two yellow eyes with whiskers/feelers/tentacles
There are spikes behind the front elbows.
Some parts of the body are very hairy and in other areas the skins is visible.  
Generally a light value for both textures.
