I love your mecha ! The details that you add to your model are quite interesting, ill keep that kind of reflexion in my mind for futher works, thank you !
Wow Testudny thanks a lot for the reply ! I spended lots of hours modeling crank and I’m super glad that you like too ! I’m impatient to see your future models and how our models evolve on the blender course! 
Hello Santi, you’re welcome ! I hope to reach that level of yours one day ^^
