There isn't any sense to it. You can have all kinds and any order of wackiness, as long as there is an overarching sense of order. I don't see any here. There isn't any overarching logic to how it works. Avatar. X-Men. Ex Machina. The best series no mater how fantastic the premise and elements found within, there is always a set of consistent rules. This character seems to be fundamentally inconsistent.
You've got this grimy realistic element going on, but at the same time this obviously unbalanced metal arm, that can turn into a revolver barrel. What is that suppose to mean? Can it fire bullets? How, the joints should be in the way. What about the hand, where does it go? If it does fire bullets, how would he not be thrown back? What pose would he assume when firing? You're mixing absurdity and realism and that just can't work without some fundamental framework this appears to be lacking.
The questions you're asking are the right ones, I know that, but I don't think its good to be seeing this as a definitive work. There hasn't been any background information as to what setting or environment this character's world/universe would be, so this just could be an early concept for all we know. The absurd elements of the design could be the same for every other character in the project-impractical, but adds to the personality of the individual
awesome concept/painting! nicely rendered with the use of textures! One thing :soon as I saw the revolver I thought of him as a tiny man( which I understand wasn't the intention) And I can't unsee it :1 anyhow: great work!
I agree with ShadowLeaper - simply amazing - you could bring back the western genre with this transformers update. The detail is beautiful the darkness just what the market loves. Look at Unforgiven it was the last big western hit I recall
