Orichalcos - An ancient memory

Something I drew about 2 or 3 years ago, when I was bored.
I think I chose a dragon in an X Clamp manga and I used it as a source of inspiration (I reproduced the general lineart and added my personal touch, so I don't think I copied, it's impossible to totally reproduce the Clamp's amazing style anyway XD) and coloured it.
Kind of crappy as it's very old, but what do you think? Should I try to draw it again?
