Fan fiction artwork

Okay, so I'm starting this fan fiction project, called Sparks of Rebellion (you'll find updates on my blog: http://beingpad.blogspot.com) and I need some artwork for it. It focuses on four main characters, but revolves around at least ten (explained on my blog) characters. The four main characters are:

Nic Osel is a Rutian Twi'lek assassin. He has a muscular build, but isn't exceptionally tall. He is relatively good looking for his species. he wears his lekkus Bib Fortuna style. He wears a black hood and thin silver plating (similar to Stormtrooper). He uses a blaster well but prefers his trusty cortosis sword, which he keeps tied around his waist on the side (like a pirate)

Nyrrika Celan is an Aargauun Human new to the bounty hunting scene. She should wear a tight black tanktop-type thing. She has wavy dark brown hair and striking green eyes. She is a little below the average human height and very thin. She wear tight, lightly-armored pants and keeps her blaster rifle on her back on a sash. Her brown shoes have hidden dart launchers.

Rycar Venitine is a Correlian bounty hunter. He has short black hair, dark eyes, and a warm but cocky smile. He wears for hunting anything armored and wearable in his ship. He quickly adapts to any weapon, but is most skilled in hand to hand combat. He keeps his knife by his side, and his darkstick nearby as well. He is 1.6 meters tall.

Deltos is a Gormak from Voss. He is tall by human standard and muscular. He has brownish-gray skin, like most members of his species, and red eyes with yellow-orange pupils. The frills on his head are a very deep red. He wears an armored suit from the Old Republic era, a suit made by his own kind and used during 3,653 BBY. He tends to keep to his Gormak rifle with an extended barrel.

These can be taken each by four different people, but please make it clear who you are doing. Reference images are on Wookieepedia. Thanks in advance, and happy arting.
