I like the style on your skin alot, theres a few things that i think need fixing though.
Your really overdoing the scratch effect (dont remember the name heh sorry) on the edges, Make the effect alot more smaller especially the width of it, and it dosent need to be down the whole edge, and need more randomization. Also I know your not finish but your really going to need some self illumination especially on the back, it looks plain without it. And finally if you follow my first crit then you could follow up with small scratches on the plates and some small dirt/dust effects.
