Undead tractor !

Hi everyone, it's been a while ! 

A new project in school, the goal is to create a "war" vehicle after studying some industrial tractor, here's my proposition ( at a WIP stage ( line-art )), the color will come after, with the character ( Undead farmer ) which also need to be completed.
