Commission: Steel Flameblade

Yo everybody. Long time no see.
I have been working on my blog lately ( [link] ) and I have not updated anithing on DA (shame on me). Mostly because I work with moving images mostly and I can´t put them here (I´d love it though).
Aaaanyway, for this commission I had to follow a very precise character description. It was a hard but rewarding task. This is, in brief, the description I had from the client:

Name: Steel Flameblade.

Nature: Half fire demon and half dragon in human form.
Powers: Black magic, fire spells and enchanted sword.

Height: about 6'6", toned physique, light skin.
Hair: black with sideburns, also black.
Face: Strong jaw, slightly pointed chin.
Eyes: Dragon-like (vertical slit pupil and extended firey iris).

Dress/Equipment: He wears mainly red and black, small portions of white interspaced for contrast. The very bottom layer of his outfit is a scalemail, the second layer is cloth, and it's made to mesh with the armor on the front of the legs, upper arms, and chest. This cloth is black on the leg and near the waist, and overlapped by a red tattered "shawl" at the top. The arms are red.
His armor includes steel, clawed gauntlets, shoulderplates (not overly massive), and spiked boots.
He wears a red and black cape, ground length and shoulder width at the top, flared wider at the bottom. It is tattered from many battles. It loops over his collarbones just inside the shoulderplates, and clasps around the neck. Wrapped over his right shoulder/collarbone is a chain. It winds down his right arm, and hangs about an inch down at the wrist, ending in a wicked spike. The chain also binds his sword to his back.

Weapon: He carries a double edged greatsword, very wide and tall like him. I would prefer that the edge was a bit on the more complex/unique side and not completely straight.The sword hangs diagonally across his back. The chain on his right shoulder binds it to his back by wrapping around the blade and then wrapping over his left shoulder to secure it. The blade is made of diamond at its center, the actual edge is made of metal with a very thin silver line at the egde. The sword has no sheath.

Props: He carries a dark book with a silver spine and silver corners. It contains his black spells, and is normally hidden away, but should not be in this case.

Composition: I would prefer him to be drawn at an angle, staring off to the right, so that as much as possible of his face is visible. The chain should be visible on his right arm, the sword be shown as fully as possible and the armor displayed adequately.
Setting: I would like him to be standing on scorched earth, possibly with a mountain in the background. The ground around him maybe revealing a charred skeleton and the smodlering remains of some armor. A tattered flag of some defeated enemy blows in the wind behind him. It's just for effect, no specific symbol required, and feel free to exclude it or hide it as much as you like. The time of day should be approaching sunset.
