It's Technic, Brick Modified 2 x 2 with Pin Hole, Rotation Joint Ball Half (Horizontal Top)
I'm working on that feeling now, we see digital mostly because of perfect aligning of parts and parts are perfectly without any scratches and so on) i'm trying to find out how to add some randomness in this stuff. BTW it looks way more realistic in link at the end of first topic (ultra hi-res link)
Scheme is looking like this - you build your model in LDD, then import it at mecabricks site,(or you can build model on mecabricks without using LDD) then export it from mecabricks like 3D model so then you can open it in most of 3D software (3D Max, C4D, Blender, etc). Then it takes some time to tune up materials correctly to match original LEGO colors, reflections, specular, shadows, add some lighting and finally render it (it takes some time depending on size of model and scene setup)
Thank you all for your opinions, i'm happy that you like it )
