Hello Cagil and welcome to the Forums! Not sure why there was no response to this before me because you have a nice model. I will have to take a look at the youtube video to see how you painted that.
Only critique that i would make is about the mud and this will vary from person to person so take it as you will. to me the demarcation line from mud to tank is to stark. The bottom of the tank looks like it just got done swimming through a mudhole while there is no mud above the fenders. It may have been better to not entirely cover the road wheels with the mud or bring some of the mud above the fenders and onto the hull.
Looking forward to your next build.
