Thank you all for your comments,
As a matter of fact, the idea of the suspension came up just a couple of days before starting the project, just when I saw that photo of the real tank, I decided to give it a try
This build was also my first time using oil paints and turpentine, and I had a very good time with it, really easy to do since turpentine allows you to "erase" and start again without problems.
Jacob, thanks for your comment about the figures, truth is that at the end of the project I was kind of without spirits to finish them because I saw the tank finished and the figures took me too long, like if seeing the tank finished made me think it was all finished.
I am practically new in this military modeling world, been making civil models in the past and I am glad to learn little by little these details and techniques that make the military vehicles to be more and more realistic.
Happy holidays to everyone!
Cheers,
Guillem
