I randomly shaded it ;)
It started as a 5minute sketch but I went a little overboard haha!

I'm a big fan of high contrast :B
I'll keep it in mind for my next work, thanks!

Fuck,this is awesome man.

:B

Thanks

Sorry Alpha, didn't see your responce, Il start once I get home, and just briefly change it :P

And if you consist on changing it yourself, try to smooth out the shading a bit, if you think that the sun should be shining in the back, add shadows heavily to the front and less to the back.

I think it's the fourth time I'm saying this, please pay attention:

I shaded completely random, to my liking, as it was a 5 minute sketch gone overboard.
I hope this clears it out :B
