Lovin' your stuff on this thread so far! And I second the suggestions, I'd definitely consider doing some freelancing for d20 companies, it's definitely good enough quality.
Here's two I'd not mind nifty art of. I realize ml3's busy, no rush, when/if you get around to them. An archdevil and one of his creations:
1) Duke Vapula, Lord of the Infernal Machine: Although Vapula can appear to mortals in nearly any guise, his true form is that of a regal-looking man with aquiline features, nearly 15 feet in height. The devil wears a cloak made from the pure-white feathers of the angels and devas slain by his mechanical creations, and his hands have the claws of a bird of prey. He is often found, as suits his personality, in the libraries of Hell, paging through this book or that, finding the facts and tidbits he uses to win souls. He is always accompanied by a fiendish griffon.
2) Iron Whipmaster: The iron whipmaster superficially resembles an iron golem, though it rather conspicuously lacks a head. A small glass window on the thing’s chest reveals a leering, demonic visage and nine iron-tipped nodules are arranged in a ring in place of a head. It has two humanoid arms. When punishing a slave, an iron whip snakes out from under its hand, and it lashes the shade with this. On occasion, Vapula gifts a mortal cultist with one or more of these monstrosities. Since it might be relevant to the drawing, the ring is motored: during this guy's main special attack, the nodules in its "head" extend to whips and flail around madly.
