I was really impressed by this! The best thing was probably how you showed that massive shot of all the cube-like structures. I thought that it would be about drug addiction, guessing from the title. The music was great too. This is truly some fantastic CGI. You rarely see that here.
I'm glad how it told a great story. I could totally associate with this poor guy. I guess he was supposed to be a robot? It really gives you the idea of an epic journey. The scene selection probably helps.
