Yurasu Shireiki

Finally here's the finished version of my comet OC.
I had some trouble picking colors and figuring out where the shadows/lights  should be. Well as you can see – I still haven't figured it out correctly. XD
Anyway my mind came to it's limit, so I just left it be, though I'm not quite satisfied. XD

Still hope it's fine for the contest.

Name: C/2001 Q4 (NEAT)

AKA: Yurasu Shireiki (The name is a combination of a few Japanese words - Yurasu means ''rock“ and Shireiki is a combination of Shi and in ''death“ and Reiki meaning ''aura“ and also refering to the healing method)

Position: flying around mostly in south celestial pole

Height: 5'5"
Weight: 523.6 lbs
Eye Color: White
Gender: Male
Personality Traits: He's calm and relaxed. Prefers to be alone, but sometimes gets a wish for some company, yet he avoids forming any deeper friendships. He likes to be independent and freely fly around exploring different places.
Body Structure: He's pretty muscular and has some stones attached to his body. His tail is formed as a consequence of him getting closer to a sun. As his body is deeply frozen, the increasing heat causes him to defrost and the dissolved particles of his body shape the glowing tail and the cloudy form around his hips. The closer to the sun he gets, the longer and brighter his tail becomes. But that can be very painful for him and shorten his lifespan.
Base Power: He is a healer, although not a very powerful one. Using his tail, he can heal external injuries of comets, asteroids and other celestial beings, but his powers don't have much effect on larger bodys such as planets and absolutely no effect on stars (suns). The reason behind that is that he uses his own melted particles to implant them into the patients body. Therefore he can't heal anything that exceeds his own body mass. Using his healing powers also shortens his lifespan. 
Close Companions: His sister.
Enemies: Doesn't have any, but is angry on a certain asteroid. Though he doesn't consider him his enemy and just hopes to never see him again.
Background: When he was younger, he had a few siblings. They were all very curious, playful and careless. They flew around aimlessly and had no worrys. But than one day a large envious asteroid came between them, attacked and separated them, pushing everyone in a different direction. Suddenly Yurasu found himself alone with his badly hurt sister. That's when he developed his healing powers to save her. 

Encounter with Earth: He was once passing by near Earth and saw that many other beings were gathered around her. The sound of their voices was slightly reaching him. They were in a good mood. The Earth seemed like a very gentle and kind being. He stopped for a second to take a better look, but than carried on his way.
