VERY nice!

I like pictures like this: the ones that have stories to tell. This robot is leaving a tall factory. Two possibilities are in my mind:
1. This robot is a mad dog, fresh out of the factory and itching to kill. His creators wisely chose to equip him with a sword, because with a gun in his hands he would be out of their control.
2. The robot is a humble construction robot, (note the arm straps, which I think could function as tool belts) who questioned his job. He accidentally uncovers the supercompany's evil intention to take over the world or something, and saves the day, defeating the would-be tyrannical overlords (judging by the blood on his sword, it seems like the battle has already been fought).

Very interesting shading style! Very unique, and the shading style differs depending on the texture being shaded. Color scheme is somewhat industrial (I picture industrial as shades of grey with occasional rusty brown) with strong influences from post-apocalyptic and/or steampunk. The character design is very unique, and I feel that you were creative with it (I could try to guess what your inspirations were, but I'd probably end up listing everything from bioshock to borderlands).

Very nice detail, a mysterious and likeable story, and bucketloads of creativity!

=D

Great Job

I love the style. The colors work nicely and the theme is great. Keep up the good work.
