Interesting glass texture.
I really really like the glass textures here, the textures for the metal is your standard every day metal meh texture but still came out nice, I prefer the left over the right simply because it looks more fleshed out and furbished. Recently did some room renders where I wasn't happy with the lightbulb since I am new to 3D art, plus I don't know how to set up lights to ignore some models and not others so that I can shine a light out of a bulb. Would be nice to know. Nice glow texture on the filament. Which 3D program was used to make it and what rendering tools?
Well with the Q&A over with, back to my opinion, I can't really rate it since it's a question posed to other artists, but I'd give it a 9 for good measure since their excellent models regardless. And your right the screw looks a tad off on close inspection. But on first glance you don't notice it, I've seen bigger mistakes from people in the industry so don't be too hard on yourself (believe me it's hard not to be) :-P.
