neat one!this one looks like a mixture of styles and designs dude. on one hand side you have this kind of walker robot with its technology...but on the other side there or those details like the grid, the rifled tubes and those round shapes on his feet which have a different feel. allmost old school like.
i would be cooler if your robot would have different front and back legs in my opinion. altering their rhickness would even do a lot. as if the factory it was built in just had ONE design of legs which were put on every war machine they constructed there ;D ...man my comparison skillz are the worst....
i personally favorize that first little thumb ! it looks more brutal and natural. with its pose it sure looks a bit exagurated! the feet touching each other in the middle . its ass reaching out . same for the head. and the massive amount of guns and riffles on his back! BUT JUST THAT looks somehow appealing to me. it has more charakter in my opinion. it looks rough and evil. could have been built by the russians just -> mounting guns over guns to add more firepower
those double rifles at the front! i really do miss em on your final design there were so cool
