what do you think?

It's a wip?
if yes, very nice. [:
7/10

well to be honest it is not a WIP :/

but why looks the front like a sketch? o:

What you mean?

I dunno how to say it in English xDD

you mean the black lines. It would look stupid without them so they are there.

the scratches you made are not uniform, I see lines of many directions,
like you scribbled all and just have painted
I would give it a 4/10, the back is really good

back is great front sucks.... the idea of the head is nice
just make the front less scribbly and the thing of the "light flash" eyes etc ruin the head a bit....
back is just great

Ah i see u what u did with the lines , did u try to make shadows on it so looks like plating on top of each other, if so, instead of drawing lines try using a drop shadow or the dodge and burn tools
