Ohmaigod man, das amazing ;w; I luuuuv all these shadows, and the light you made, and those metalic parts are just amaaazing >8C gimme your skills. And the background is also really cool, not so detailed, but fits the art just perfect :U
Someone said on a forum once that it was because he had no screen time and no development/back story but was countered by a person who said that he didn't really need development if his only motives are greed and power, cause it shows what can happen if the wrong person gets into power.
I'm in general a mlp fim fan (wich you probably already knew) In general, I like it how villians, or just other characters, get developed more. And since Trixie didn't get that much stream time, I'd love to see her become friends with the mane 6 like forgive and froget, as well as Gilda and the others (wich right now I can't come up with)
