A personal project I have been working on my free time. All the detail was added using alpha maps in sculpt mode. Rendered in cycles and final touches done in photoshop. I include some different views of the model. Hope you guys like it 
Nice work! Maybe the complete robot would look nicer 
Awesome work! It would be nice to see the whole character and not just the upper part
Robot’s face kind of reminds me of The Scream by Edvard Munch.
Finish the whole robot and do a whole scene.
21st Century update!
Just a thought.
Great use of Alphas! it is paint with vertex paint???
Thanks! Yeah next time I will make a complete one hehe
Now that you mention it, it does look a little like The Scream haha, cheers mate!
Thanks Tonatiuh! Yeah I used vertex paint to change the color and the materials
Great modelling, and I think it would be better if the helmet more like metal. What you think?
Thanks so much! Do you mean making the material look more like metal?
thanks mate!
great advice, thanks!
Excellent! Nice design! Amazing texturing anyway…
