Hi everyone.
At last time i worked a lot on this project for my portfolio.
I was making this scene for practice, because modeling a tank gave a lot of experience and knowing some modeling rules in blender. Making this render was really hard for me and pushed me to learn a lot about cycles materials, shaders, lightening.
At all, im satisfied how cycles handled this project and gave me nice result.
Render: Cycles
Render time: 11 hours 8 minutes
Samples: 2000
I can’t see a tank, just some snow…
But in seriousness, great job! 
Well need little bit work on texture tank, special on machine gun and i think it would be much better. And yeah model tank look so good! Snow and trees look great!
The modeling and texturing look very good, but some of the materials on the top seem too clean.
