Space tunnel

Good day guys, spend some time upgrading my materials for a project and I thought I just re-release it with an updated render!

And of course, share some critic, every bit of information is helpful for my next projects!

Thanks in advance and enjoy <3

PS: Doesnt worked with my AMD card well. Either the kernels still suck or 1 GB is just not enough :frowning:
Took me nearly 2 hours to render on my CPU in 720p T_T
