Siphon color

ALL HAIL to my new digital tablet. (Sung to the tune of hail to the chief) hail to the tablet it’s the tablet and it needs hailing, hail to the tablet or I’ll stab you in the back to basta...

Ahem... sorry about that. Yes my first official coloring using my new Wacom digital tablet, OH YEAH! I really felt to reach the next level in my art I needed to advance to a digital tablet and boy am I glad I did. You’ll notice there’s none of the original line work (except on the jacket). I’ve wanted to test out a digital coloring without the black outline for a while now. I consider this image the best I’ve done thus far. I hope you enjoy.

Character description;
This is an image of one of my superheroes. Her name is Siphon. There’s an old (and very bad) design of her here on deviant art. I really like this design. Her symbol is a diamond shape with an indented S in it. I hope you can make it out.
I’ve had the concept of this superhero for a while. Her power is the ability to absorb, store and redirect most energy forms. She cannot produce energy beyond the natural human abilities but she can store what she produces (heat, kinetic, neural electric). The energies she can absorb store and redirect include; any type of charged particle (electricity), electromagnetism (radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.), Mechanical energy (elastic, kinetic, surface, sound) and thermal energy. She is not compatible with nuclear energy, chemical energy and gravitational energy.
It’s a great concept; her power has infinite applications and diversity. By controlling the emission of one of several energy forms she can fly. She can absorb all sound waves she comes in contact with creating absolute silence in that vicinity, then directing them at whoever she wishes. The multiplied sound waves would hit her target almost deafening them. She could absorb all the kinetic energy in a punch from the hulk and redirect it back at him with a single touch. She can absorb light, creating darkness, and then use it to blind her enemies. Drain any electrical device. And of course her projectile blasts are almost limitless in their strength (she’s only limited by the available energy and considering the presence of the sun, there’s a lot of it around).
She does have weaknesses. She can’t absorb the kinetic energy of a bullet (it’s moving too fast) She is vulnerable to slashing attacks and chemical attacks. There’s a lot of ways to bring her down. Invincible super heroes tend to lose their appeal, like superman (no offence superman).
