I liked how you combined Trons lighting effect with Vador. It's a very unique design. The one and only thing that bothers me is the c4d. It doesn't seem to blend correctly with the piece. I don't know if it's the color or the placement or the overall shape itself. It just looks a little off. Honestly other than that it looks great.
I think it is probably the bubble effects I used. Looking at them now I hate the way they look. Might update with a v2 tomorrow minus the bubble stocks.
Also, I didn't do the render. Sorry to disappoint you. I just thought it was really BA looking.
